Question

Find the voltmeter and ammeter reading in the above circuit.

• A. 0V , 1 A
• B. 0V , 0A
• C. 5V, 1 A
• D. 5V , 0.5A

Answer 1

The correct option is A

0V , 1 A

The upper Resistor is shorted with an ideal wire so all the current flows through it instead of passing through the 10-ohm resistance.So no potential difference.

So effective resistance in the circuit is 10 ohm only and potential in the circuit is 10 v so total current is by ohm’s law.

V=IR. I= $\frac{V}{R}$ = $\frac{10}{10}$ = 1A
