Question

A battery of = 2.00 V and internal resistanceR = 0.450 is driving a motor. The motor is lifting a 2.0N mass at constant speed v = 0.50 m/s. Assumingno energy losses, find the current i in the circuit. Enter thelower current. 1. 5.74*10^-1A 2. Enter the higher current? 3. Find the potential difference V across the terminalsof the motor for the lower current.? 4. Find the potential difference V acrossthe terminals of the motor for the higher current.?
