What is the relationship between power and bulb brightness (intensity)?

Explanation:

Power of an electrical appliance is given by :

P = VI

Here,

V is the voltage

I is the current

From the above formula for power, we find that power is directly proportional to the voltage of the circuit. If a single bulb is there in the circuit, increasing the voltage of the bulb will increase its power, which in turn increases its bulb brightness or intensity.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
