Question

power of 200v electrical device is 500w. caculate the current through this device​

Answer 1

Answer:

I = 2.5 A

Explanation:

P = 500 W , V = 200V

We know that ,

P = VI

So, I = P/V

I = 500/200

I = 2.5 A

Answer 2

The current through this device​ is 2.5 A.

Given: The power of a 200 V electrical device is 500 W.

To Find: The current through this device​

Solution:

• We know that the relation between power and a potential difference is given by the formula,

        Power (P) = Potential difference (V) × Current (I)            .....(1)

Coming to the numerical, we are given,

       Power (P) = 500 W, Potential difference (V) = 200 V

Putting respective values in (1), we get;

       Power (P) = Potential difference (V) × Current (I)  

   ⇒ 500 = 200 × I

   ⇒ I = 500 / 200 A

         = 2.5 A

Hence, the current through this device​ is 2.5 A.
