Electrical Circuit Theory Quiz 1

Ohm's Law relates the voltage across a resistor, the current through it, and its resistance. What happens to the current if the voltage is doubled while the resistance remains constant?

• The current is halved

• The current is doubled

• The current remains the same

• The current becomes zero
