Question

An alternating voltage is connected in series with a resistance R and an inductance L . If the potential drop across the resistance is 200 V and across the inductance is 150 V, then the applied voltage is (A) 350 V (B) 250 V (C) 500 V (D) 300 V

Tardigrade Admin · Accepted Answer

The applied voltage is given by V=√VR2+VL2 V=√(200)2+(150)2=250 text volt

Q. An alternating voltage is connected in series with a resistance $R$ and an inductance $L .$ If the potential drop across the resistance is $200 V$ and across the inductance is $150 V$ , then the applied voltage is

350 V

250 V

500 V

300 V

The applied voltage is given by
$V = V_{R}^{2} + V_{L}^{2}$
$V = (200)^{2} + (150)^{2} = 250 volt$
