Question

Please help!?!?
in the diagram, if a light bulb is placed at D&b is closed (as shown), what will happen?

a. The light bulb will be off
b. The light bulb will be shorted
C. The light bulb will be dimmer than normal
D. The light bulb will be on

Answer 1

Since bulb is connected in the closed circuit at the position of D

as well as switch B is also closed in that position so the current will flow through the bulb and bulb will glow in that position

So the most appropriate correct option will be

D. The light bulb will be on

Answer 2

Answer:

D. The light bulb will be on

Explanation:

When a bulb is placed at D it works like a load and will draw the current. The circuit will remain open until the switch B is closed. Once B is closed, the current will start flowing through the bulb and it will turn on.

It can be understood through an experiment as will. You can connect a small LED with a battery and see for yourself that the LED turns on.
