Ohm’s Law Quiz Practice Quiz | ohm's law

Q: Ohm's Law describes the relationship between which three quantities?

Voltage, Current, and Resistance — Ohm's Law specifically deals with voltage, current, and resistance in a circuit.

Q: What is the formula for calculating voltage (V) using Ohm's Law?

V = I * R — Voltage is calculated by multiplying current and resistance: V = I * R.

Q: If a circuit has a current of 2 Amperes and a resistance of 10 Ohms, what is the voltage?

20 Volts — Using V=I*R, V = 2A * 10 Ohms = 20V.

Q: What is the unit of measurement for electrical current?

Ampere (A) — Current is measured in Amperes (A).

Q: Which of the following statements best describes Ohm's Law?

The current through a conductor between two points is directly proportional to the voltage across the two points. — Ohm's Law states current is proportional to voltage, given constant resistance.
