g (a) what is the voltage output of a transformer used for rechargeable flashlight batteries if its primary has 515 turns, its secondary has 8 turns, and the input voltage is 114 v? v (b) what input current is required to produce a 4.00 a output? ma (c) what is the power input? w

Respuesta :

For the given data voltage output is 2.06v,input current to get 4 A output is 0.07A and power output is 14.25j.

From equation (1) we get,

Vs=125×8/485=2.06V

Therefore the output voltage of the transformer is 2.06 V

(b)

From equation (2) we get

Ip=4×8/485=0.07A

Therefore to get an output current of 4 A, the input current should be 0.07 A.

c)

p=E/t

=114/8

power output =14.25j

The voltage that a device, like a generator or a voltage regulator, releases into the air is known as the output voltage. A constant voltage is maintained by voltage regulators. Electricity is produced by spinning turbines that interact with magnets when they are powered by a fuel source, such as sunlight, coal, or nuclear energy.
