Question

To make the bulb glow, it is advisable___

• A. to connect the terminals of the battery to only one terminal of the bulb.
• B. to connect the terminals of the battery to two different terminals of the bulb.
• C. to connect the terminals of the bulb to one of the terminals of the battery.
• D. to connect one terminal of the battery to one terminal of the bulb, and keeping other terminals open.

Answer 1

The correct option is B

to connect the terminals of the battery to two different terminals of the bulb.

To make the bulb glow, it is advisable to connect the terminals of the battery to two different terminals of the bulb. This arrangement leads to glowing of the bulb. Remaining arrangements like connecting both terminals to one terminal of either component or connecting only two terminals, and keeping other two open does not work. This is an open circuit. We need a closed circuit, so that the current flows through the circuit, and makes the bulb glow.
