Question: 1 / 400

Ohm's law describes the relationship between which two electrical quantities?

Voltage and energy

Current and resistance

Voltage, current, and resistance

Ohm's law is a fundamental principle in electrical engineering that establishes a relationship between voltage, current, and resistance. According to Ohm's law, the voltage (V) across a conductor is proportional to the current (I) flowing through it and the resistance (R) of the conductor. This relationship is expressed mathematically as V = I × R, where voltage is measured in volts, current in amperes, and resistance in ohms.

When analyzing this relationship, voltage represents the potential difference that drives the current through the circuit, while resistance is the opposition to the flow of current. This means that for a given resistance, an increase in voltage will lead to an increase in current, illustrating how all three quantities interact within electrical circuits. Understanding this relationship is crucial for analyzing and designing circuits effectively.
