1 Introduction to Electric Current Basic Concepts Electric current is the flow of electric charge in a conductor. It is measured in amperes (A) using an ammeter. Electric current can be either direct (DC) or alternating (AC). The flow of electrons in a conductor creates electric current. Photo by Pexels
2 Ohm’s Law Voltage, Current, Resistance Ohm’s Law defines the relationship between voltage, current, and resistance. It is represented by the formula: V = IR. Voltage (V) is the potential difference measured in volts. Resistance (R) opposes current flow, measured in ohms (Ω). Photo by Pexels
3 Types of Electric Current AC and DC Direct current (DC) flows in one direction only. Alternating current (AC) changes its direction periodically. AC is used in household power supply and DC in batteries. Both types have different applications in electrical systems. Photo by Pexels
4 Measuring Electric Current Devices and Tools Ammeters are used to measure the electric current in a circuit. Clamp meters can measure current without disconnecting the circuit. Multimeters can measure voltage, current, and resistance. Proper measurement is crucial for electrical safety and efficiency. Photo by Pexels
5 Conductors and Insulators Material Properties Conductors allow electric current to flow easily through them. Insulators resist the flow of electric current. Common conductors include copper, aluminum, and gold. Rubber, plastic, and glass are common insulators. Photo by Pexels
6 Applications of Electric Current Everyday Use Electric current powers household appliances like refrigerators, microwaves, and lights. It is essential in industrial machinery and equipment. Transportation systems, such as electric trains and cars, use electric current. Medical devices also rely on electric current for operation. Photo by Pexels
7 Electric Circuits Pathways of Flow Electric circuits provide a path for the flow of current. Simple circuits include a power source, conductors, and a load. Complex circuits can have multiple components and configurations. Proper circuit design enhances functionality and safety. Photo by Pexels
8 Safety Measures Handling Current Always ensure proper insulation of wires to prevent electric shock. Use circuit breakers to protect against overcurrent. Follow safety guidelines when working with electricity. Regular maintenance ensures the safety of electrical systems. Photo by Pexels
9 Electric Power Energy and Work Electric power is the rate at which electrical energy is transferred by an electric circuit. It is measured in watts (W). Power (P) can be calculated using the formula: P = IV. Efficient power usage is crucial for sustainability. Photo by Pexels
