Question

Define Alternating current and give some examples of it.

Answer 1

Hint: AC is an electric current that in contrast to DC periodically reverse direction, in only which flows one direction. The alternating current’s usual waveform in most electric circuits is a sine wave, which corresponds to a positive half period with a positive direction and vice versa.

Complete step-by-step solution:
Alternating current abbreviation, AC flow of electric charge that periodically reverses. It starts, grows to maximum say from zero, reverse, in the opposite direction, decreases to zero, a maximum, to the original value returns gains and repeats this cycle indefinitely. The interval of time between the attainment of a definite value on two successive cycles, is called a period, the frequency is the number of cycles or periods per second, and in either direction the maximum value is the amplitude of the alternating current. By the generators the currents that are produced or Turbine are the AC currents and from our Home power sockets the current we get are AC current. For example: mostly electrical appliances like FAN, Bulb, AC, Motors etc. work on AC current.

Note: Direct current’s flow does not change regularly, as opposite to the alternating current. In the area, AC moves safely over longer distances which can provide more power. Electrons continue to turn directions forward and reverse.AC was first tested using a Dynamo Electric Generator, using Michael Faraday’s principles in the year 1832.
