Question

The voltage drop across a standard resistor of 0.2 Ω is balanced at 83 cm. The magnitude of the current, if the standard cell emf of 1.53 V is balanced at 42 m is ___________ (a) 13.04 A (b) 10 A (c) 14.95 A (d) 12.56 A I had been asked this question during an interview.

Answer 1

The correct choice is (c) 14.95 A The explanation: Voltage drop per unit length = \frac{1.53}{42} = 0.036 V/cm Voltage drop across 83 cm length = 0.036 × 83 = 2.99 V ∴ Current through resistor, I = \frac{2.99}{0.2} = 14.95 A.
