Question

Электрокипятилтник мощность 110 ВТ рассчитан на напряжение 220В.Определите силу тока и сопротивление кипятильника. Заранее спасибо!

Answer 1

Жиза, только было 200

Answer 2

P=110 Вт

U=220 В

I=?

P=I*U

I=P/U=110/220=0.5A

Answer 3

Calculation of Current and Resistance in an Electric Kettle

To determine the current and resistance of an electric kettle, 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: - Power (P) of the electric kettle = 110 W - Voltage (V) across the kettle = 220 V

We can use the formula: P = V * I, where P is power, V is voltage, and I is current.

To find the current (I), we rearrange the formula as follows: I = P / V

Substituting the given values, we have: I = 110 W / 220 V

Calculating the value: I = 0.5 A

Therefore, the current flowing through the electric kettle is 0.5 Amperes.

To find the resistance (R) of the kettle, we can use Ohm's Law: R = V / I

Substituting the given values, we have: R = 220 V / 0.5 A

Calculating the value: R = 440 Ω

Therefore, the resistance of the electric kettle is 440 Ohms.

In summary: - The current flowing through the electric kettle is 0.5 Amperes. - The resistance of the electric kettle is 440 Ohms.

Please note that these calculations assume the electric kettle operates under ideal conditions and does not take into account any losses or variations in the electrical system.
