True: The commutator is the part of a motor that enables the coil to rotate using direct current., Electro motive force convert other forms of energy, such as electrical energy, into mechanical energy., DC Motors are mostly powered by cells and batteries., No current is produced when the armature is not being rotated in electric generators., The more solenoid coils in a motor, the stronger the electromagnet., AC motors use electromagnets rather than permanent magnets., According to Faraday's law, any change in the magnetic environment of a coil of wire will cause a voltage (EMF) to be "induced" in the coil., Most appliances at home is powered by electricity generated by generators in Power Plants., False: An electric motor is a device that converts mechanical energy into electrical energy., A generator is a device that converts electrical energy into mechanical energy.,
