Ohm's Law - Technical MCQs

Q1:

If voltage across a resistance doubles

A the current is halved

B the resistance doubles

C the current is unchanged

D none of the above

ANS:D - none of the above

The question says 'a resistance', which means the resistance is not change.

When the Voltage is doubled in a resistance, from V=IR, then the only variable that will be changed is the current to double.

So, answer D.
