Question

3. Спираль электрической плитки изготовлена из нихромовой проволо- ки длиной 13,75 ми площадью поперечного сечения 0,1 мм2. Плитка рассчитана на напряжение 220 В. Определите силу тока в спирали плитки.

Answer 1

Ответ:

I=U/R

R=Ро* l/S

Ро(Удельное сопротивление)нихрома=1,1

R=1,1* 13,75/0,1=151,25

I=220/151,25=(примерно)1,45

Answer 2

Calculation of Current in the Electric Stove Spiral

To determine the current flowing through the spiral of an electric stove, we can use Ohm's Law, which states that the current (I) flowing through a conductor is equal to the voltage (V) across the conductor divided by the resistance (R) of the conductor. Mathematically, this can be expressed as:

I = V / R

In this case, the voltage (V) is given as 220 V. To find the resistance (R) of the spiral, we need to know the resistivity (ρ) of the material and the dimensions of the spiral.

The spiral of the electric stove is made of a nichrome wire with a length of 13.75 m and a cross-sectional area of 0.1 mm². However, we need the resistivity of the nichrome wire to calculate the resistance.

Unfortunately, the search results did not provide the necessary information to determine the resistivity of nichrome wire. Therefore, we are unable to calculate the current flowing through the spiral of the electric stove at this time.
