In LR circuit (shown in figure), current is lagging by `pi/3` in phase with applied voltage, then select correct alternative:

A

`L=10/(sqrt(3)pi)H,i=10A`

B

`L=10/(pi)H,i=5A`

C

`L=10/(sqrt(3)pi) H,i=5A`

D

`L=(sqrt(3))/(10 pi)H,i=5A`

Text Solution

Verified by Experts

`(X_(L))/R=sqrt(3)rArr x_(L)=Rsqrt(3)`
`i=100/(sqrt((10sqrt(3))^(2)+(10)^(2)))=5A`
`L=(10sqrt(3))/(100pi)=(sqrt(3))/(10 pi) H`

When an alternating voltage of 220 V is applied across a device P , a current of 0.25 A flows through the circuit and it leads the applied voltage by a angle pi/2 radian. When the same voltage source is connected across another device Q , the same current is observed in the circuit but in phase with the applied voltage. What is the current when the same source is connected across a series combination of P and Q ?

An alternating voltage of frequency f is applied across a series LCR circuit.Le f_(r) be the resonance frequency for the circuit.Will the current in the circuit lag, lead or remain in phase with the applied voltage when (i) f gt f_(r) ,(ii) f lt f_(r) ? Explain your answer in each case.

The current in the LCR circuit shown in the figure is observed to lead the voltage in phase. Without making any other change in the circuit, a capacitor, of capacitance C_0 is (appropriately) joined to the capacitor C. This results in making the current, in the joined to the capacitor C. This results in making the current, in the modified' circuit, flow in phase with the applied voltage. Draw a diagram of the modified circuit and obtain an expression of C_0 in terms of Omega , L and C.
