Ohm's Law Quiz

Ohm's Law

• Ohm's law describes the relationship between voltage, current, and resistance in a conductor.
• It states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.

Resistance

• The unit of resistance is the Ohm (Ω).

Effect of Voltage on Current

• If the voltage across a resistor is doubled, the current flowing through it will also double, provided the resistance remains constant.

Test your knowledge of Ohm's law with this quiz! Learn about the relationship between voltage, current, and resistance, and find out the unit of resistance. See if you can answer questions like what happens to the current when the voltage across a resistor is doubled while the resistance remains constant.
