sorry if wrong section- help with Q on inductive reactance - revision homework

[technokaz]

hi all, can someone if the following answer is correct. would as teacher but 2 days till class.

a coil of inductance of 0.2H is connected across a 230V 50Hz supply. What will be the current flowing in the circuit, if we assume that there is no resistance?

XL= 2pie fL

XL= 2pie * 50 * 0.2 = 62.832ohms

I=U/XL = 230 / 62.832 = 3.661A

is this correct ( if we assume that there is no resistance? - this part just giving me doubts on answer.

thanks everyone.

Yes thats correct. It customary to round up the value to say 1 decimal point ie 3.7A
