Question

На баллоны электрической лампы написано 60Вт;120В. Определите силу тока в лампе, если её включить в сеть с напряжением на которое она рассчитана.​

Answer 1

Ответ: 0,5А

Объяснение:

Дано:

Р=60Вт

U=120В

--------------

I-?

Р=UI

I=P/U=60/120=0,5А

Answer 2

Calculating Current in the Lamp

To determine the current in the lamp when it is connected to a power supply with the voltage it is rated for, we can use the formula P = V * I, where P is the power in watts, V is the voltage in volts, and I is the current in amperes.

Given: - Power (P) = 60 watts - Voltage (V) = 120 volts

We can rearrange the formula to solve for the current (I): I = P / V

Substitute the given values: I = 60W / 120V

Calculation

I = 0.5 amperes

So, the current in the lamp, when it is connected to a power supply with the voltage it is rated for, is 0.5 amperes.
