Question

The main advantage of A.C power transmission over D.C power transmission over’ long distance is
(a) AC transmit without much loss of energy
(b) less insulation problem
(c) less problem of instability
(d) easy transformation.

Answer 1

Option A is Correct.

AC transmits without much loss of energy.

What is Alternating Current?

• The current which reverses its direction and polarity at regular intervals of time is known as Alternating Current.
• The cycle of Alternating current starts from zero and reaches a positive maximum and then comes back to zero. It then reverses its direction and reaches the negative maximum and then comes back to zero.
• Changing from a higher potential to a lower potential is one of the advantages of Alternating Current.

• Transformers are used to convert high A.C voltages to low voltages and vice versa.
• Alternating current is mostly used at home and offices.
