Question

. In an A.C., which one of these holds true ?
(a) Potential in the circuit is high
(b) Polarity changes continuously at a constant rate
(c) Polarity does not change continuously
(d) Resistance in the circuit is very low​

Answer 1

Answer:

option c is the correct answer

Answer 2

In an A.C. Polarity Changes continuously at a constant rate

Explanation:

• In AC the Current flow back and forth at each interval or cycle.

• The current comes from main power line or normally in household is Alternating current.

• Advantage of having alternating current over direct current is that it is cheap in changing the voltage of the current

• Other is the loss which happens when carry current for large distances is less in alternating current as compared to direct current
