A capacitor used for power factor correction is single phase circuit decreases
-
Assertion (A): In an R-L circuit having high inductance, the rise of current is very slow.
Reason (R): The time constant of R-L circuit is L/R.
-
The distance between the plates of a parallel plate capacitor is d. The dielectric is in two parts, each of equal thickness but dielectric constants ∈1 and ∈2 respectively. The total capacitance will be proportional to
-
An air cored coil has an inductance of 0.3 H. If another coil has an iron core of μr = 500, the remaining quantities being the same, the inductance of the second coil will be
