help I need c and e
VA Hw4b Computational x net/web/Student/Assignment-Responsesvsubmit?dep 0652415 C D www.webassign The primary coil of a transformer has 3,477 loops. The secondary coil has 602.666 loops. The primary coil has a sg A current and 42 v a.) is this a step up or step down transformer How do you know? Choose one of the following. O It is a step-up transformer because all transformers are step up transformers. It is a step down transformer because all transformers are step-down transformers, 1t is a step up transformer because the secondary has more loops than the primary. O It is a step down transformer because the primary current is greater than the primary voltage It transformer because the primary current is greater than the primary voltage, is a step up G It is a step down transformer because the secondary has mare loops than the primary b.) Determine the power of the primary coil. c) Assuming no losses, determine the power of the secondary coil, X w d.) Calculate the voltage in the secondary coil. x v e.) Calculate the current in the secondary coil My Notes o Asi Tour
Explanation / Answer
c) Since there is no power loss,
Out put power = Input power
= I1*V1
= 89*42
= 3738 W
d) V2/V1 = N2/N1
V2 = V1*(N2/N1)
= 42*(602666/3477)
= 7279.83 volts
e) P1 = P2
I1*V1 = I2*V2
==> I2 = I1*(V1/V2)
= 89*(42/7179.83)
= 0.52 A
