Homework Statement
A power plant produces energy at a voltage of V = 15435 V. Before being sent along long distance power lines this electricity is sent through a transformer with 112 turns in the primary coil and 8613 turns in the secondary coil. If the wires have an efficiency of 99.60 percent and a resistance of 1323 ohms, what current flows through these wires?
Homework Equations
V = IR
V1/V2 = n1/n2
The Attempt at a Solution
V1/V2 = n1/n2
15435/V2 = 112/8613
V2 = 1186979.063
V = IR
I = V / R
= 1186979.063 / 1323
= 897.1875 A x 99.6%
= 893.5988A
But this seems to be the wrong answer. Help please!
