In the following figure , grade the bulb in order of their brightness :

Grade the bullbs in order of their brightness (All bubls are identical)

The above configuration shows three identical bulbs , Grade them in order of their brightness.

In the following figures, the bulbs in Figure A and D glow, but the bulbs in Figure B and C do not glow. Give reason.

Observe the following figure. Which bulb will fuse ?

In the given picture, if we remove bulb B from its holder, the brightness of bulb A will:

When the switch is closed in the circuit as shown in the following figure, the light bulb become bright in an inperceptibly short-time interval, and then gradually goes out. We interpret this to mean that

The two electric bulbs of same power are connected in parallel circuit. If one bulb is glowing and then another bulb is switched on, then brightness of the first bulb increases, decreases or remians unchanged. Expalin.
