Question

What is the resistance of a heating coil on an electric stove that has a current of 25 A flowing through it and uses 0.24 kV? Round to two significant digits (one decimal). *

Answer 1

Resistance of a heating coil on an electric stove that has a current of 25 A flowing through it and uses 0.24 kV

-

Given. - Current drawn =25 A

Voltage = 0.24 kV.

In current electricity

Voltage =Current × Resistance

V = I × R

So

Resistance= Voltage/Current

$r = v \div i$

In given problem

V= 0.24 kV or 0.24×1000 V

$r = \frac{0.24 \times 10 {}^{3} }{25}$

so the resistance of the given coil is =9.6ohm
