Question

The readings of the voltmeter and ammeter in the circuit shown in the diagram are respectively

• A. 5 V, 3 A
• B. 7 V, 3 A
• C. 5 V, 1 A
• D. 7 V, 1 A

Hint:

In circuits with resistors and voltage sources, use Ohm’s law ($V = IR$) to find the relationships between voltage, current, and resistance.

Answer 1

The Correct Option is A

By applying Ohm’s law and using the given circuit values, we can calculate the voltage across the components and the current through the circuit. The correct readings for the voltmeter and ammeter are 5 V and 3 A, respectively.
