In any network
of linear impedances the current flowing at any point equal to algebric
sum of currents caused to flow at that point by each of the emf taken
separately with all other emfs reduced to zero. The statement
represents.

In an R-L-C circuit, v(t) = 20 sin (314 t + 5 p/6) and i(t) = 10 sin (314 t + 2p/3). The p.f of the circuit is

A capacitor is considered to be completely charged in __________ time constant.

Consider the following statements associated with two port networks.

1. Z₁₂ = Z₂₁
2. Y₁₂ = Y₂₁
3. h₁₂ = h₂₁
4. AD - BC = 1

Assertion (A): The number of basic loops is equal to number of links.

Reason (R): The graph theory helps in choosing independent variables in circuit analysis.

In attenuation band, `beta` is an odd multiple of p.

The peak factor is the ratio of
