3. A resistor is a
passive two-
terminal electrical
component that
implements
electrical
resistance as a
circuit element.
What is Resistor?

4. Electronic
symbol for
Resistor

5. The resistor's current I in amps (A)
is equal to the resistor's voltage V
in volts (V) divided by
the resistance R in ohms (Ω): V is
the voltage drop of the resistor,
measured in Volts (V).

15. The power rating of
a resistor is the
specification given with
a resistor that serves to tell
the maximum amount
of power that
the resistor can withstand.
if a resistor has a power rating of 1/4 watts, 1/4 watts is
the maximum amount of power that should be fed
