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