Question

find the power of electric device of resistance1200 r which a consent of 2A
​

Answer 1

Answer:

the power of electric device is 4800 watts

Explanation:

p=vi

p= i^2r    (v=ir)

p= 2*2*1200

p=4800 watts

Answer 2

Given: R=1200ohm (Resistance)

I = 2 Ampere ( Current)

Solution:

•We have to find Potential Difference (V) first .

So, V= IR

= 1200×2 Volts

= 2400 V ( Volts)

Now..

Power = Potential Differences × Current

= 2400×2

= 4800 Watt. (ANSWER)
