Answer:

Explanation:

Formula

Voltage_p * Current_p = Voltage_s * Current_s

Comment

What the formula means is the voltage multiplied by the current in the primary = voltage multiplied by the current in the secondary.

Givens

Vp =100 v

Ip = 6 amps

Vs = x

Is = 0.75 amps

Solution

100 * 6 = 0.75* x

600 = 0.75 x                  Divide both sides by 0.75

600/0,75 = 0.75x/0.75

800v = x

What you have here is a step up transformer. It has a relatively small voltage (100 volts ) on the primary which the transformer changes to 800 volts in the secondary.

Answer

800 volts.
