Question

What is the power of a lamp connected to 12v when carries 2.5

Answer 1

Answer:

30 watts

Explanation:

Acc. to the relationship of Power with Voltage and Current,

We have,

P = I × V

= 25/10 × 12

= 30 Watts

Therefore Power = 30 watts

Answer 2

Answer:

30wats

Explanation:

Different streetlights consume different amounts of energy. Incandescent lamps typically range from 25-150 watts, fluorescent lamps range from 18-95, metal halide lamps range from 50-400 watts, and high pressure sodium lamps range from 50-400 watts.

How do you calculate the power of a lamp?

In a resistor, it is dissipated as heat, and in a light bulb, it i222s dissipated as heat and light. P=IV=(VR)V=V2R. P=IV=I2R=V2R. The power supplied from the battery is equal to current times the voltage, P=IV.

so given v=12

               i=2.5

              p=iv=12x2.5

                       =30 wats
