Question

draw a schematic diagram of an electric circuit comprising of 3 cells and an electric bulb, ammeter, plugkey in the on mode and another with same components but with two bulbs in parallel and a voltmeter across the combination
​

Answer 1

I hope it's help u dear

Answer 2

To draw:

• Circuit with 3 cells, an electric bulb, ammeter and plugkey in the on mode.

• Circuit with same components but with two bulbs in parallel and a voltmeter across the combination .

Solution:

Few things to remember before drawing circuit:

• In the first case, when 3 cells have been mentioned, we will assume that all the three cells have been connected in series with similar polarities.

• Ammeter (modified galvanometer) will always be connected in series with the circuit.

• Voltmeter (modified galvanometer) will always be connected in parallel to the circuit across which the potential difference needs to be measured.

• Always remember to close the circuit by closing the plug-key. Or else , the circuit will remain open.
