The induced voltage on the pick-up coil with n1=20 turns is 293 mv. after adding a number of turns the new value of the induced voltage becomes 1.8 v. what is the new number of turns, n2, on the pick-up coil? express the answer as a whole number.

To solve the problem it is necessary to take into account the concepts related to induced voltage.

The induced voltage, when the flow is constant, becomes directly proportional to the number of turns of the coil, that is

Getting the relationship we have to

Re-arrange to find N_2 we have

Replacing with our values

There is 123Turns at the second coil.

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.
