Question

The reading in the ideal voltmeter (V) shown in the given circuit diagram is :

• A. 5V
• B. 10V
• C. 0V
• D. 3V

Answer 1

Answer: (C)

0V

Answer 2

The total voltage across the resistors in the circuit is $V_{total} = 8V + 5V + 5V = 18V$. However, the voltmeter is placed across the 5V and 5V resistors, where the potential difference across them is zero, so the reading on the voltmeter is 0V.
