Parallel Circuits - Engineering

Q1:

A sudden increase in the total current into a parallel circuit may indicate

A a drop in source voltage

B an open resistor

C an increase in source voltage

D either a drop in source voltage or an open resistor

ANS:C - an increase in source voltage

Agree @Saurabh.

As mentioned that this is PARALLEL CIRCUIT, Current can increase only in two conditions:

1) Either resistance decreases (In this case total resistance can be decreased only if another resistor is added in parallel).
Or
2) Voltage, applied to the circuit, increases.

So, the answer should be [C].
