Question

What is the resistance of a 1000 w heater marked for 230 v

Answer 1

answer is here ........

Answer 2

The resistance of the heater is 52.9 Ohms.

Explanation:

Given that,

Power of the heater, R = 1000 W

Voltage, V = 230 V

To find,

Resistance of the bulb.

Solution,

The power of an electrical appliance is given by :

$P=V\times I$

or

$P=\dfrac{V^2}{R}$

$R=\dfrac{V^2}{P}$

$R=\dfrac{(230)^2}{1000}$

R = 52.9 Ohms

So, the resistance of the heater is 52.9 Ohms.
