What is the change in experiment if battery is connected between `B` and `C` and galvanometter is connected across `A` and `C` ?

What is the change in experiment if battery is connected between B and D and galvanometer is connected across A and C ?

When an a.c source is connected across a resistor

When an a.c source is connected across a resistor

A capacitor is charged by connecting a battery across its plates. It stores energy U. now the battery is disconnected and another identical capacitor is connected across it. What will be the energy stored by both capacitors of the system?

Cells of emfs 10V and 20V are connected as shown. When an ammeter is connected across A and B its reads 1A, when connected across B and C it reads 5, when connected across A and C it reads 3A, find the resistance of the ammeter (in Omega )

In Fig. 7.48 , each of the segments ( e.g., AE , GM, etc.) has resistance r . A battery of emf V is connected between A and C . Internal resistance of the battery is negligible. If a potentiometer circuit having gradient k is connected across the points H and C , the balancing length shown by the potentiometer is
