Define altern...

Question

Define alternating current ? what is the frequency of AC in India ? Name teh device used to control AC in the circuit ?

Open in App

Solution

the current which changes its direction with time is called alternating current.in alternating current the electrons not only move in forward direction but they move back and forth.
in india 50hz frequency is used.
device which are used in circuits to control ac are transformer,capacitors,inductors.

Q. Assertion :If the frequency of alternating current in an ac circuit consisting of an inductance coil is increased then current gets decreased. Reason: The current is inversely proportional to frequency of alternating current.

Q. Which device is used to control the flow of current in the circuit?

Q. An ac ammeter is used to measure current in a circuit. When a given direct current passes through the circuit, the ac ammeter reads
