उत्तर

With the suggested configuration, he will be able to light the bulb. He can connect one of the bulb’s terminals straight to the electric cell’s negative terminal. As a result, he won’t require any additional cable for our electric circuit. The diagram depicts the needed setup:

A battery is to be formed by joining 3 dry cells with connecting wires. Show how will you connect the wires by drawing a diagram.


In an electric circuit, a battery and a bulb have been connected and the battery consists of two cells of equal potential difference. If the bulb is not glowing, then which tests will you perform in order to find out the reason for the bulb not glowing?


Find the odd one out and give its explanation.


What is the potential difference?


Higher Order Question

A student made a circuit by using an electric cell, a switch, a torch bulb (fitted in the bulb holder), and copper connecting wires. When he turned on the switch, the torch bulb did not glow at all. The student checked the circuit and found that all the wire connections were tight.

  • What could be the possible reason for the torch bulb not glowing even when the circuit appears to be complete?

In the following circuits (Figure), heat produced in the resistor or combination of resistors connected to a 12 V battery will be

Write a short note on the different electrical circuits.


Name the device which is used to measure the strength of the electric current in an electric circuit.


Assertion: People struck by lightning receive a severe electrical shock.

Reason: Lightning carries very high voltage.


Set up the circuit shown in Figure again. Move the key to ‘ON’ position and watch carefully in which direction the compass needle gets deflected. Switch ‘OFF’ the current. Now keeping rest of the circuit intact, reverse the connections at the terminal of the cell. Again switch ‘on’ the current. Note the direction in which the needle gets deflected. Think of an explanation.
