Determine the current power in the light bulb if, at a voltage of 5V, the current in it is 100mA.

As we know from the current school physics curriculum, the current power can be determined through the product of voltage and current.

Let us determine how many watts the current power in an electric bulb will be expressed, when from the condition of the task we know that the current strength is 100 mA, while the voltage is 5 volts:

100 mA = 100: 1000 = 0.1 A

5 * 0.1 = 0.5.

Answer: Under such initial conditions, the current power in the light bulb will be 0.5 watts.
