Question

why the bulb glow brighter and brighter when we connect batters in series connection​

Answer 1

Answer:

The voltage drop across each resistance is the same as the applied one. Hence most of the supplied voltage (the electrical energy) reaches the bulb. Hence it glows brighter. Now in the case of series combination of resistors, the effective resistance of the circuit increases.

Hope it helped :)

Answer 2

Explanation:

12. A block of mass 50kg is moving on a rough

horizontal floor (Ux = 0.4) under the action of a

force 2002N directed at 45° to the horizontal.

If the block moves 3m, what is: Mamel.

(1) The work done by applied force, frictional

force, gravity & normal reaction.

(D) Total work. (g = 10 m/s2)
