Answer 2

Answer:

Hey Mate here's ur Answer ↓

Alternating current means its polarity (direction of flow of current ) changes alternately from +ve to -ve and -ve to +ve. Frequency means the number of times the signal (current/voltage) reaches its maximum or minimum in one second. In India the frequency is 50 Hz. AC is safer than DC for very high Voltages.
