O 0.33 ohms
O 0.42 ohms​

Answer 1

Answer:

A resistance value of an unknown resistor is calculated using the formula R=d

I

V

whereV and I be the readings of the voltmeter and the ammeter respectively. Consider the circuits below. The internal resistance of the voltmeter and the ammeter(R

V

and R

G

respectively) are finite and non zero.If the resistance of voltmeter is R

1

=1 kΩ and that of ammeter is R

G

=1 Ω, the magnitude of the percentage error in the measurement of R (the value of R is nearly 10 Ω) is
