WebThe p.d. across XY is decreased and the balanced length XN is increased. 83. In the potentiometer circuit below, the moveable contact is placed at N on the bare wire XY, such that the galvanometer shows zero deflection. The resistance of the variable resistor is now increased. What is the effect of this increase? WebApr 8, 2024 · The galvanometer deflection is temporary and it lasts as long as the bar magnet is in motion. There won't be any deflection when the bar magnet is held stationary anywhere. When the magnet is moved away from the coil, the galvanometer shows deflection in the opposite direction indicating the direction of induced current in the …
