Voltage and Current

Q1: If the current in a circuit equals 0 A, it is likely that the

A voltage is too high

B resistance is too low

C circuit has a short

D circuit is open

ANS:D - circuit is open

Even tough voltage is too high practically it is impossible for current to be zero. So in that case the only option is circuit is open which offers infinite resistance. R = V/I. R - resistance. V - voltage. I - current. If I = 0 then R = infinity.
