A network in which all the elements are not physically separable but considered as separable while solving problems is called a

A transformer of 15Ω resistor is connected across secondary winding having voltage of 150 V, then find the primary voltage across the transformer when there is a supply current of 2 A flowing across it?

In the electric circuit, if input voltage V_IN is a constant DC, then:



i.   Resistor R will bypass the capacitor C
ii.  Capacitor C will be charged
iii. Capacitor will be discharged

A horizontal sectional conductor 150.0 cm long with weight 9.00 g having 0.600 T magnetic
field is directed towards in west direction. Find the magnitude and direction of current in order to make the conductor weightless?

What will be the mutual inductance in pair of coils where a 6A current in one of the coil causes flux in other coil with 2000 turns which changes to 12x10^-4Wb/turns?

If two capacitors C₁ = 10 μF and C₂ = 20 μF are connected in parallel with third capacitor C3= 30 μF in series, then the equivalent capacitance results as:

The figure below shows magnetic field directed out of page with moving rod in right direction. Find the direction of induced current in the rod?
