Question

Спираль электрической плитки изготовлена из нихромовой проволоки длиной 13,75 м и площадью поперечного сечения 0,1 мм2Плитка рассчитана на напряжение 220В. Определить силу тока в спирали плитки.

Answer 1

R=1,1*13,75/0,1=151,25 Ом I=220/151,25=........

Answer 2

Calculating the Current in the Electric Stove Spiral

To calculate the current in the electric stove spiral, we can use the formula:

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

First, we need to calculate the resistance of the spiral using the given information.

The resistance (R) of the spiral can be calculated using the formula:

Resistance (R) = Resistivity (ρ) x (Length / Cross-sectional Area)

Given: - Length of the nichrome wire = 13.75 m - Cross-sectional area of the wire = 0.1 mm^2 - Voltage (V) = 220 V

Let's calculate the resistance first.

Calculating Resistance (R)

Using the formula: Resistance (R) = Resistivity (ρ) x (Length / Cross-sectional Area)

Given: - Length (L) = 13.75 m - Cross-sectional area (A) = 0.1 mm^2

We need the resistivity (ρ) of the nichrome wire to proceed with the calculation. However, the resistivity value is not provided in the given question or search results. Without the resistivity value, it's not possible to calculate the resistance and subsequently the current in the spiral.

If you have the resistivity value of the nichrome wire, please provide it, and I can proceed with the calculation.
