Question

1. A cell, a resistor, a key and ammeter are arranged as s own in the circuit diagrams of Figure12.1. The current recorded in the ammeter will be

Answer 1

where is diagram of this question??????

Answer 2

The current recorded by the ammeter in all the three circuits will be the same.

Explanation:

The formula for Finding Current in an electric circuit:

I = V / R

R indicates the resistance in all the three circuits.

Since V and R are equal in all the three cases. Hence, the current will be recorded as the same in all the three circuits by the ammeter and there will be only a change in the Potential difference of the circuit as it is connected in a series circuit.

Therefore, the current recorded by the ammeter in all the three circuits will be the same.
