The high resistance causes most of the voltage to drop … WebJan 17, 2024 · A meter bridge is set-up as shown, to determine an unknown resistance X using a standard 10 ohm resistor. The galvanometer shows null point when tapping-key is at 52 cm mark. The end-corrections are 1 cm and 2 cm respectively for the ends A and B. The determined value of X is (a) 10.2 oh (b) 10.6 ohm (c) 10.8 ohm (d) 11.1 ohm

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? WebIt means the battery is good, and working. When electricity from the battery travels around the coils, it creates a magnetic field. This field is what causes the compass to spin. If the …
