A step up transformer has 250 turns on its primary and 500 turns on it secondary. When the primary is connected to a 200 V and t

Zina [86]

Answer:

2000 W

Explanation:

First of all, we need to find the output voltage in the transformer, by using the transformer equation:

$\frac{V_1}{N_1}=\frac{V_2}{N_2}$

where here we have

V1 = 200 V is the voltage in the primary coil

V2 is the voltage in the secondary coil

N1 = 250 is the number of turns in the primary coil

N2 = 500 is the number of turns in the secondary coil

Solving for V2,

$V_2 = N_2 \frac{V_1}{N_1}=(500) \frac{200 V}{250}=400 V$

Now we can find the power output, which is given by

P = VI

where

V = 400 V is the output voltage

I = 5 A is the output current

Substituting,

P = (400 V)(5 A) = 2,000 W
