Question

1. a good component in a shorted rl parallel branch _________.

measures 0 volts across it
causes minimum current
causes current to decrease
measures the applied voltage across it

Explanation:

In a parallel circuit, when one branch (RL in this case) is short - circuited, the voltage across all parallel branches is the same as the voltage across the short - circuit. A short - circuit has a very low (ideally zero) resistance. According to Ohm's law \(V = IR\), for a short - circuit \(R\approx0\), and the voltage across it \(V = 0\) (since \(I\) is finite for a practical source). So, any good component in a parallel branch with a short - circuited RL branch will have \(V = 0\) across it.

Answer:

A. measures 0 volts across it
