Overview
Electric voltage and current are fundamental concepts in electricity. Voltage, measured in volts, is the potential difference that drives electric charge through a circuit, while current, measured in amperes, is the actual flow of that charge. Understanding these concepts is crucial for working with...
Key Terms
Example: A battery provides a voltage of 9 volts.
Example: A current of 2 amperes flows through a wire.
Example: A resistor has a resistance of 5 ohms.
Example: Using Ohm's Law, if V = 10 volts and R = 5 ohms, then I = 2 amperes.
Example: A simple circuit includes a battery, wires, and a light bulb.
Example: In a series circuit, if one bulb goes out, all bulbs go out.
