Question

in LR circuit ac source has voltage 220v if the potential difference across inductor is 176v then potential difference across rsisitane will be __ v​

Answer 1

Answer:

ans is 132V

Explanation:

for inductor.

v(t) = Vsin(wt+π/2);

176 = 220cos(wt) >>> os(wt) = 0.8

now for resistance;;

v(t) = vsin(wt)

v(t) = 220*√1-cos²(wt)

   = 220*0.6

   = 132V ans...
