If L, C and R are the self inductance, capacitance and resistance respectively, which of the following does not have the dimension of time?
Given below are two statements :
Statement I : A time varying electric field is a source of changing magnetic field and vice-versa. Thus a disturbance in electric or magnetic field creates EM waves.
Statement II : In a material medium, the EM wave travels with speed $$v = {1 \over {\sqrt {{\mu _0}{ \in _0}} }}$$. In the light of the above statements, choose the correct answer from the options given below.
The current flowing through an ac circuit is given by
I = 5 sin(120$$\pi$$t)A
How long will the current take to reach the peak value starting from zero?
Two coils of self inductance L1 and L2 are connected in series combination having mutual inductance of the coils as M. The equivalent self inductance of the combination will be :
