QUESTION 3 A rаcing cаr uses аn engine and an electric mоtоr tо power its wheels. (a) The electric motor can only operate at maximum power for part of each lap of the race. The electric motor has a maximum power output of 1.2 × 105 W. The electric motor transfers 4.0 × 106 J of energy when it operates at maximum power. Calculate the amount of time the electric motor can operate at maximum power. (3) (b) The diagram shows a simplified view of a direct current (d.c.) electric motor. (i) State what is meant by the term direct current. (1) (ii) Explain the purpose of the brushes and the commutator in the d.c. motor. (3) (c) The electric motor in the racing car can also be used as a generator to charge a battery pack. It is known as a motor generator unit (MGU). The rotating wheels of the car cause the magnets in the MGU to spin near a coil of wire. This induces a current in the coil when the coil is connected to the battery pack. (i) Name the energy store of the battery pack that increases when the battery pack is being charged. (1) (ii) Explain why the kinetic energy store of the car must decrease when the MGU charges the battery pack. (3) [11]
