each other with exactly two electrically common nodes with
the same voltage across each component.

22. Slow-Blow Fuse
A slow-blow fuse, also known as a time-
delay fuse or slo-blo fuse, is a type of fuse
designed to handle temporary current surges
without immediately blowing.
Capacitive Fuse
A capacitive fuse is not a standard type of
fuse. It's important to understand that the term
"capacitive fuse" is not a widely recognized or
standardized term in the electrical engineering
field.

23. inductive fuse

protect electrical equipment and
devices from overcurrents and
short cicuits in high voltage
applications. they are specifically
designed to interupt or isolate the
cicuit in case of fault, preventing
damage to the equipment and
ensuring safety.

25. WHICH IS TRUE OF A SERIES DC MOTOR WITH NO LOAD?
Tends to stop or not start - switching-off or application of reverse
polarity (reversing the power supply to motor).
Has reversed direction - Incorrect component installation
Maybe damaged by excessive speed - it will run at a dangerous speed. It
will burn out. A DC series motor wouldn't be allowed to operate in no
load condition
Becomes an AC generator - Inverters are an essential part of any
electronic device that converts direct current (DC) power to alternating
current (AC) power.

refer to variations in electrical
quantities such as voltage, current, or
power over time.

27. Sine Wave
Cycle
is a smooth, periodic oscillation that represents
a mathematical curve defined by the sine
function.
refers to one complete waveform, which includes one full
oscillation from the starting point to the peak, down
through the equilibrium point to the trough, and back to
the starting point.

28. 41
Capacitor
is a two-terminal electrical device that can
store energy in the form of an electric
charge.
Parllel Circuit
has two or more paths for current to flow through.

29. Example of Two Capacitors in Parallel
Formula:
Ceq = C1 + C2
Advantage of Parallel Connections:
Increase Capacitance
LowerEquivalent Impedance
Voltage Sharing

30. If two capacitors of the same value are
connected in parallel, the total capacitance
will increase. The total capacitance in parallel
is simply the sum of the individual
capacitance.

31. If two capacitors in parallel are changed so that one increases
in value and the other decreases, the total capacitance will
depend on the new values of each capacitor.
▪︎When a capacitor's value increases, it adds more capacitance
to the total, meaning the system can store more charge.
▪︎When a capacitor's value decreases, it subtracts from the
total capacitance, reducing the system's ability to store charge.

32. Half-Wave Rectifier
- A Half-wave rectifier uses one diode to convert
an AC signal into pulsating DC. It allows only one
half of the AC waveform (either positive or negative)
to pass through, blocking the other half.
Full-Wave Center-Tap Rectifier
- A Full-wave center-tap rectifier uses two diodes
and a center-tapped transformer. It rectifies both
halves of the AC waveform, producing a full-wave
rectified output.

33. Full-Wave Bridge Rectifier
- uses four diodes arranged in a bridge configuration to
convert the full AC waveform into pulsating DC. It
efficiently rectifies both halves of the AC signal.
Split-Type Rectifier
- is less common and may refer to rectification that
uses separate paths for each half of the AC waveform. It
can involve different methods for rectifying each side of
the waveform, though it doesn't specifically require four
diodes.

34. Increases- refer to rises in voltage, current, or power,
enhancing device performance and efficiency.
Decreases- involve reductions in voltage, current, or
resistance, which can significantly affect circuit
performance. Lower voltage may lead to insufficient
power delivery, while decreased current can limit device
functionality.

35. Is infinite- often relates to idealized conditions, such as
infinite resistance in open circuits or infinite
capacitance in certain theoretical contexts.

36. Peak Reverse Voltage (PRV)
refers to the maximum reverse voltage that a diode can withstand
without breaking down or conducting in reverse. It’s crucial for ensuring
the diode operates safely in its reverse bias condition without being
damaged.
Blow Up Voltage
often referred to in the context of electrical components, is the voltage
at which a component, such as a diode or capacitor, fails
catastrophically, typically leading to permanent damage or destruction.
This is usually higher than the rated maximum voltage, and operating at
or beyond this voltage can cause failure.
47

37. WORKING VOLTAGE
refers to the maximum continuous voltage that can be applied to a
component, device, or insulation without causing damage or failure during
its normal operation. It is the highest voltage that the equipment can handle
safely and reliably over time without breaking down.
BREAKDOWN VOLTAGE
is the minimum voltage at which an insulating material or electrical
component begins to conduct electricity uncontrollably, leading to failure
or damage. It occurs when the electric field becomes strong enough to
ionize the material, causing a sudden surge of current.

38. Crystal Diode
Is a type of point-contact diode that
uses a metal wire pressed against a
semiconductor crystal. The crystal acts
as a cathode and the wire acts as an
anode. The diode conducts when the
anode voltage is greater than the
cathode voltage. Crystal diodes were
originally made from crystalline
minerals such as galena and used in
microwave receivers and detectors.
They are also called cat’s whisker
diodes or crystals

39. Silicon Diode
A silicon diode is a two-terminal semiconductor
device constructed from a silicon crystal. It has a
PN junction, with one side doped with atoms
containing more electrons (N-type) and the other
side doped with atoms containing fewer electrons
(P-type). The P-type side is called the anode, and
the N-type side is called the cathode.

41. ZENNER
is a special type of diode designed to operate in
the reverse breakdown region, where it allows
current to flow in the reverse direction when a
specific voltage is reached.
LIGHT EMITTING
is a semiconductor device that emits light when
current flows through it. Electrons in the
semiconductor recombine with electron holes,
releasing energy in the form of photons.

43. BREAKDOWN
WORKING
refers to the process of analyzing or dividing something into
smaller, more manageable parts to understand it better. It can
also refer to a failure or malfunction in a system, machine, or
process.t
refers to the process of engaging in tasks, activities, or labor with the
aim of achieving a specific goal, fulfilling responsibilities, or earning
compensation. It involves applying effort, skills, time, and often
knowledge to accomplish something, whether in a professional,
academic, or personal context.
