Ohm's Law - Technical MCQs

Q1:

If current through a resistance is halved

A the resistance is halved

B the voltage is halved

C the voltage doubles

D none of the above

ANS:B - the voltage is halved

Current and Voltage have a proportional relationship. If one goes up or down in a circuit, the other goes up or down as well.

Current and Resistance have an inverse relationship. If one of these goes up, the other goes down, and vice versa.
