Can we use galvanometer to measure alternating current ?

Text Solution

AI Generated Solution

To determine whether a galvanometer can be used to measure alternating current (AC), we can analyze the working principle of the galvanometer and the nature of AC. ### Step-by-Step Solution: 1. **Understanding the Galvanometer**: - A galvanometer is an instrument that measures small electric currents. It operates based on the principle of torque acting on a coil placed in a magnetic field. The deflection of the needle is proportional to the current flowing through the coil. 2. **Current Types**: ...

A DC ammeter cannot measure alternating current because

`AC` changes its direction

`DC` instruments will measure the average value

`AC` can damage the `DC` instrument

`AC` produces more heat

A : The ammeters and volmetrs used for measuring alternating current and voltages have non-uniform divisons on their scales. R : The instruments used for measuring alternating current and voltage are based on heating effect of current.
