Current Electricity

Current electricity is the flow of electric charge through a conductor. It is the movement of electrons within a circuit, and is essential for the operation of most electrical devices.

Key Concepts

• Electric Current: The flow of electric charge through a conductor. It is measured in Amperes (A).
• Voltage: The force that drives the electric current. It is measured in Volts (V).
• Resistance: The opposition to the flow of electric current. It is measured in Ohms (Ω).
• Ohm's Law: Describes the relationship between voltage, current, and resistance: V = IR, where V is voltage, I is current, and R is resistance.
• Series and Parallel Circuits: Circuits can be connected in series or parallel, affecting the overall current, voltage, and resistance in the circuit.

Study Guide

1. Define electric current and its units of measurement.
2. Explain the relationship between voltage, current, and resistance using Ohm's Law.
3. Compare and contrast series and parallel circuits, including their effects on current and voltage.
4. Calculate the total resistance in series and parallel circuits.
5. Understand the concept of electrical power and its calculation using P = IV, where P is power, I is current, and V is voltage.
6. Describe the effects of resistance on the flow of current in a circuit.
7. Identify common household circuits and their components.
