an ac circuit with a total resistance of r has an rms current of i. the circuit wraps around an iron core transistor with 50 loops. the secondary coils, leading to a different circuit, wrap with n loops. the secondary circuit has a total resistance of 40 ω. what is the rms current in the secondary circuit (6 points)? assigned values for 15.0 ω r = , i = 5.0 amp, and n = 18

current is 13.88 A

Explanation:

given data

no of loops = 50 loops

resistance = 40 Ω

R = 15.0 Ω

I = 5.0 amp

N = 18

to find out

rms current

solution

we will apply here transformed principle that is

v(s) / v(p) = I(p) / I(s) = N(s) / N(p)   1

here p is primary and s is secondary

put here all these value

5 / I(s) = 18 / 50

I(s) = 250 /18

I(s) = 13.88

so current is 13.88 A
