Important Questions on Types of Current
A current that always flows through an electric device in the same direction is called direct current or . The polarity (positive and negative) of a direct current is fixed. A current that reverses direction at equal intervals of time is called the alternating current or . The polarity (positive and negative) of an alternating current is not fixed. Both and can be used for lighting and heating. Some electric devices like the television need to operate. In such cases, an adapter or a device is fitted into them to convert from the mains supply to .
