A small electric car overcomes a 250 N friction force when traveling 30 km/h. The electric motor is powered by ten 9 V batteries connected in series and is coupled directly to the wheels whose diameters are 50 cm. The 300 armature coils are rectangular, 10 cm by 15 cm, and rotate in a 0.66 T magnetic field.
(a) How much current does the motor draw to produce the required torque?
A
(b) What is the back emf?
____V
(c) How much power is dissipated in the coils?
____W
(d) What percent of the input power is used to drive the car?
_____%
