Question

In the given circuit, the voltmeter and the electric cell are ideal. Find the reading of the voltmeter (in volts)​

Answer 1

Answer:

1 Volt

Explanation:

Both resistors are in series

Thus the current flowing through each resistor is same , which is same as current flowing through the circuit

V = IR   Ohm's Law

where V = Voltage of battery = 2 V

I₁ = Current flowing through circuit = ?

R₁ = resistance in circuit = 1 + 1 = 2 Ohm (since resistors are connected in series)

2 = I x 2

∴ I₁ = 1 A

∴ V across AB = I₁ x R (between AB)

                        = 1 x 1 = 1 Volt
