Alternating Cur...

If $$L$$ denotes the inductance of an inductor through which a current $$I$$ is flowing, then the dimensional formula of $$LI^2$$ is 

An alternating emf of angular frequency $$\omega $$ is applied across an inductance. The instantaneous power developed in the circuit has an angular frequency : 

The rms speed of molecules of a gas is 200 m/s at $$27 ^ { \circ } C$$ and 1 atmosphere pressure.The rms speed at $$127 ^ { \circ } C$$ and double pressure is

Let $$\ell, r, c$$ and $$v$$ represent inductance, resistance, capacitance and voltage, respectively. The dimension of $$\dfrac{\ell}{rcv}$$ is $$SI$$ units will be:

For LCR series resonant circuit_______

In an A.C. circuit a capacitor of $$1 \mu F$$ value is connected to a source of frequency 1000 rad/sec. The value of capacitive reactance will be 

In the given figure the impedance of the circuit will be

When 100 volt DC source is applied across a coil, a current of 1 A flows through it. When 100 V AC source of 50 Hz is applied to the same coil, only 0.5 A current flows. Calculate the inductance of the coil.

In the only capacitive circuit, A.C voltage is 

if value of R is changed then
