Question

Ток какой силы протекает в нагревательном элементе электрической плиты, если напряжение равно 220 В, а сопротивление 91 Ом.(Результат вырази в единицах СИ, округли до целых.)

Answer 1

Вроде как сила тока равна отношению напряжения к сопротивлению
I=U/R=220/91= 2,417 округляем до целых равно 2 А

Answer 2

Calculating Current in the Heating Element of an Electric Stove

To calculate the current flowing through the heating element of an electric stove, we can use Ohm's law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) between them. The formula for Ohm's law is:

I = V / R

Where: - I = current in amperes (A) - V = voltage in volts (V) - R = resistance in ohms (Ω)

Applying Ohm's Law to the Given Values

Using the given values: - Voltage (V) = 220 V - Resistance (R) = 91 Ω

We can calculate the current (I) using the formula:

I = V / R

Substituting the given values: I = 220 V / 91 Ω

Calculating the Current

Calculating the current using the given values: I ≈ 2.42 A

Therefore, the current flowing through the heating element of the electric stove is approximately 2.42 amperes when the voltage is 220 volts and the resistance is 91 ohms.
