Question

if rating of any appliance is 200W-200V, then calculate its resistance​

Answer 1

Answer:

R = 200 ohms.

Explanation:

Here, P = 200 W

and   V = 200 V

It is known that, $P = \frac{V^{2}}{R}$   [R is the resistance]

=>  $200 =\frac{200^{2}}{R}$

=>  R = 200 ohms.

Answer 2

Here, P = 200 W

and V = 200 V

It is known that, $P = \frac{V^{2}}{R}$

[R is the resistance]

$=> 200 =\frac{200^{2}}{R}$

=> R = 200 ohms ANSWER
