Sensitivity of potentiometer can be increased by

In a potentiometer a cell of e.m.f 2V gives a balance point at 30cm. If the cell is replaced by another cell and the balance point shifts to 60cm.What is the e.m.f of the other cell?​

When the position of cell and galvanometer in a Wheatstone bridge is inter-changed, its balanced condition

An electric bulb is rated 220 V and 100 W. Power consumed by it operated on 110 V is

Meter Bridge or Slide Wire Bridge is a practical form of

When Wheatstone bridge is in balance condition, the current through galvanometer will be

The resistance in ohms in the four arms of a Wheatstone bridge are as follows. In which combination of the following is the bridge balanced?​

Two bulbs A and B are rated 100 W, 120 V and 10 W, 120 V respectively. They are connected across a 120 V source in series. Calculate the current through each bulb.​

Wheatstone bridge is used to measure

The Wheatstone bridge and its balance condition provides a practical method for the determination of
