Question

An inductor is connected in series with a resistor. When a 15 v , 50 hz alternating voltage source is connected across this series combination the voltage dropacross the inductor is 5 v, the voltage drop across the resistor will be

Answer 1

Answer:

100HZ

Explanation:

Answer 2

as we all know in ac circuit we add or substract any quantity in phasor form so here is your answer

let the voltage drop across resistor is V

(15)*2=(5)*5+(V)*2

225=25+(V)*2

225-25=(V)*2

V=√200

V=14.14

i hope you understand

its my first answer if any mistake in language please ignor
