Question

В настольной лампе, включенной в разметку с напряжением 220 В, течет ток с силой в 2 А, Каково сопротивление лампы? запишите ответ числом в Ом.​

Answer 1

Ответ:

I=U/R

R=U/I

R=220/2=110 Ом

Answer 2

Calculating the Resistance of the Lamp

To calculate the resistance of the lamp, we can use Ohm's law, which states that the resistance (R) is equal to the voltage (V) divided by the current (I). In this case, the voltage is 220 V and the current is 2 A.

Using the formula: R = V / I

Substituting the given values: R = 220 V / 2 A

Calculating the resistance: R = 110 Ω

So, the resistance of the lamp is 110 ohms.
