Question

what is meant by alternating current?

Answer 1

a flow of electricity that changes direction regularly many times a second

Answer 2

The electric current that changes direction or polarity after a fixed time interval is called alternating current or AC. The polarity (+ and-) is not set therefore in AC. In our nation the electricity supplied to our homes and industry is alternating current (AC).

• In our nation the alternating current frequency (AC) is 50 Hz.

• The alternating Current with 50 Hz frequency switches the polarity 100 times in a second.

Alternating current does not display a magnetic influence, as its polarity continues to shift in turn.
