A battery of ε = 2.90 V and internal resistance R = 0.500 Ω is driving a motor. The motor is lifting a 2.0 N mass at constant speed v = 0.50 m/s. Assuming no energy losses, find the current i in the circuit.
A.Enter the lower current.
B. Enter the higher current.
C. Find the potential difference V across the terminals of the
motor for the lower current.
D. Find the potential difference V across the terminals of the
motor for the higher current.
