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?

325 volts

Explanation:

Given that,

Self - inductance of a coil, L = 6.5 H

The change in current in the coil,

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

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

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
