dont u think some data is missing?????[7][7]

From DC eqn. R=10 ohm

IN AC: f=50 Hz,V_AC=150V

Vrms=150/√2

I=Vrms/Z

ab kya karen??????????????

ya main kuch bhool raha hoon.......[7]

R = 10 ohm
in Ac
10 = 150 /√R² + w²L²
= 150 /√R² + (2pie 50)²L²
125 = (2pie 50)²L²

L = 35.5 mH

is it correct ...

V = √5/9*150
