What current is taken by the lamp when it is connected to a 220 v mains supply? what is the resistance of the lamp
eimsori [14]

Answer:

Given parameters

Potential difference (V) = 220 V

Power of lamp 1 (P1) = 100 W

Power of lamp 2 (P2) = 60 W

Both the bulbs are connected in parallel. Therefore, the potential difference across each of them will be 220 V, because no division of voltage occurs in a parallel circuit.

We know that

Power = Voltage x Current

P = V x I

I = P/V

Lamp 1:

I1 = P1/V

I1 = 100/220

I1 = 5/11 A

Lamp 2:

I2 = P2/V

I2 = 60/220

I2 = 3/11 A

Net current (I) = I1 + I2

I = 5/11 + 3/11

I = 8/11

I = 0.7273 A

Hence, current drawn from the line is 0.727 A

Hope this helps!

What are the movements of boiling water? I'm looking for if they speed up, like that sort of thing. Not how, not why, just what
fgiga [73]
When a substance is heated, the molecules begin to vibrate faster and the space between molecules increases. So it would be speeding up.

Why do fields store potential energy? an object in the field has charge, fields don’t store potential energy, stationary objects
SpyIntel [72]

Answer:

Hey

Your answer would be:

stationary objects within the field will move when realesed.

The reason why is because fields store potential energy as you know. when something is stationary it has potential, but when it is released that potential energy turns into kinetic energy.

this made me think of a funny joke:

A man was about to jump off of the Empire State Building when a physicist from below yield, Wait don't! you have so much potential!

lol always cracks me up.
