Question

Вызначте напряжение на клеммах электрической плиты если Сопротивление ее спирали 0.3 ком, а за 6 минут прошел заряд 240 кл

Answer 1

I=q/t
I=240/360=0,7А
U=IR
U=0.7*300=210В
думаю
что это задача про лампочку
с напряжением 220В

Answer 2

Calculating Voltage on the Electric Stove

To calculate the voltage on the electric stove, we can use Ohm's law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R), or V = I * R.

Given: - Resistance (R) of the stove's coil = 0.3 kΩ - Charge passed through the coil in 6 minutes = 240 kC (kiloCoulombs)

Applying Ohm's Law

First, we need to calculate the current (I) flowing through the coil using the formula I = Q / t, where Q is the charge and t is the time.

Let's calculate the current: - Charge (Q) = 240 kC - Time (t) = 6 minutes = 6 * 60 seconds = 360 seconds

So, I = 240 kC / 360 s = 0.67 kA (kiloAmperes)

Now, we can use Ohm's law to find the voltage (V): - Resistance (R) = 0.3 kΩ - Current (I) = 0.67 kA

Using the formula V = I * R, we get: V = 0.67 kA * 0.3 kΩ = 0.201 kV

Result:

The voltage on the electric stove's terminals is approximately 0.201 kV.
