Question

Какая мощность расходуется лампочкой, потребляющей 0,5 А, если напряжение на клемах лампочки 110 В? Помогите решить пожалуйста...

Answer 1

P=u*I. ; p=0,5*110=55 вт

Answer 2

Calculation of Power Consumed by a Light Bulb

To calculate the power consumed by a light bulb, we can use the formula:

Power (P) = Voltage (V) × Current (I)

Given that the current (I) is 0.5 A and the voltage (V) across the terminals of the light bulb is 110 V, we can substitute these values into the formula to find the power consumed by the light bulb.

Power (P) = 110 V × 0.5 A

Calculating this:

Power (P) = 55 Watts

Therefore, the power consumed by the light bulb is 55 Watts.

Please note that this calculation assumes the light bulb operates under ideal conditions and does not take into account factors such as resistance, efficiency, or power factor.
