Question

A 250v bulb passes a current of 0.3a. Calculate the power in the lamp.

Answer 1

Answer:

75 W

Explanation:

V = 250 V

I = 0.3 A

So, P = VI = 250 * 3/10 = 25*3 = 75 W

Answer 2

Answer:

The power in the lamp is P=75W

Explanation:

Current is a glide of electrical fee carriers, generally electrons or electron-poor atoms. The not unusualplace image for modern is the uppercase letter I. The trendy unit is the ampere, symbolized via way of means of A.

Current is described because the motion of water in a selected direction. An instance of modern is whilst a river actions closer to a waterfall. (1) The glide of electrons thru a circuit. Measured in "amperes."

Current in amps (fee flowing in coulombs according to 2d) Potential distinction in volts (power transferred in joules via way of means of every coulomb) Power (= power transferred electrically from the energy deliver according to 2d, in joules/2d or watts (Power = VI)

so given problem

V=250v

I=0.3A

P=vi

which means that

P= 250x0.3

P= 75W
