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.
Draw the circuit diagram for the series connection.
In which of the following circuits are the bulb connected in series?
Assertion: People struck by lightning receive a severe electrical shock.
Reason: Lightning carries very high voltage.
Assertion: In an open circuit, the current passes from one terminal of the electric cell to another.
Reason: Generally, the metal disc of a cell acts as a positive terminal.
Overloading of electric circuits can lead to short-circuiting.
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.
