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?
Wheat stone bridge follows
P/Q = R/S
So 2/3 = 4/6
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
