Question

Напряжение на зажимых эликтрического утюга 220 В,сопротивление нагревательного элемента утюга 50 Остальные. чему равна сила Тока в нагревательном элементе?

Answer 1

решение:
I=U/R
I=220:50=4,4 А

Answer 2

Calculation of Current in the Heating Element of an Electric Iron

To calculate the current in the heating element of an electric iron, we need to use Ohm's Law, which states that the current flowing through a conductor is equal to the voltage across the conductor divided by the resistance of the conductor.

Given: - Voltage on the terminals of the electric iron: 220 V - Resistance of the heating element: 50 Ω

Using Ohm's Law, we can calculate the current in the heating element as follows:

Current (I) = Voltage (V) / Resistance (R)

Substituting the given values:

Current (I) = 220 V / 50 Ω

Calculating the result:

Current (I) = 4.4 A

Therefore, the current flowing through the heating element of the electric iron is 4.4 Amperes.

Please note that the above calculation assumes that the resistance of the heating element remains constant and does not change with temperature. In reality, the resistance of the heating element may vary slightly with temperature, which can affect the actual current flowing through it.
