What will be the reading in the voltmeter and ammeter of the circuit shown in fig. |
|
Answer» Inpedance of the circuit, `Z = sqrt(R^(2) + (X_(L) - X_(C ))^(2))` `= sqrt(45^(2) + (4 - 4)^(2)) = 45 Omega` Reading of ammeter, `I_(v) = (E_(v))/(Z) = (90)/(45) =2 A` Reading of Voltmete, `V = (X_(L) - X_(C )) I_(v)` `= (4 - 4) 2 = 0` |
