The resistance of a circuit is measured from the relation R= P/I2, where P is the power fed into the circuit and I is the current flowing through it.
If the limiting errors in the measurement of power and current are respectively ± 1.0% and ± 1.0%, then what will be the limiting error in measurement of resistance ?
A. ± 3.0%
B. ±0.5%
C. ± 1.5%
D. ±3.5%
