unknown conductor or inductor ?
In a series LCR circuit ,current=11A when applied voltage=220V.Voltage across unknown capacitor=220V.If value of resistor=20 ohm then voltage across unknown conductor is_____

See ... the voltage across resistor is = I*R = 11*20 = 220 V
Also net voltage = { VR2+(VL2-VC2) }1/2
and net voltage is given 220 volts
=> 2202 = VR2+(VL2-VC2) = 2202 + (VL2-2202)
=> VL=220 Volts
How come the answer is 200V !!!
I also calculated it ... I mean one can say even without pen/paper that the Voltage across the inductor will be 220V coz voltage across capacitor is 220V (they both have to cancell each other)
heyyy dude this is wrong ?
u hav provided answer in ? only 220 v
then y askin same
In a series LCR circuit ,current=11A when applied voltage=220V.Voltage across<< unknown capacitor=220V.>>If value of resistor=20 ohm then voltage across<< unknown conductor>> is_____
chek ur ? a gainnn
