Explanation:
For an ideal circuit, the resistance will come out to be simply
R
=
V
I
=
6
3
=
2
Ω
However, for a non-ideal ammeter, resistance of ammeter is not zero and hence, measured voltage is the sum of voltages across ammeter and resistance. In other words, measured voltage(
V
) is more than the actual voltage across the resistor(
V
R
) or
V
>
V
R
.
Hence, measured resistance (
2
Ω
) is more than the actual resistance.
