Question

A coil with a self-inductance of 6.5 H carries a current that is changing at a rate of 50 A/s. What is the induced EMF in the coil?

Answer 1

325 volts

Step-by-step explanation:

Given that,

Self - inductance of a coil, L = 6.5 H

The change in current in the coil,
`(dI)/(dt)=50\ A/s`

We need to find the induced EMF in the coil. The induced emf in terms of self inductance is given by :

`\epsilon=L(dI)/(dt)\\\\\epsilon=6.5* 50\\\\\epsilon=325\ V`

So, the induced EMF in the coil is 325 volts.
