Question

calculate power in watt,if current is 5A,pd in volt is 4 and resistance is 600 in a voltmeter
​

Answer 1

Answer: Given:-

Power ,P = 800 W

Current ,I = 4 A

Potential Difference ,v = 900 v

To Find:-

Time ,t

Solution:-

We have to calculate the time

Using this Formula We get

• P = VIt

Where,

P is the Power

V is the Potential Difference

I is the Current

t is the time taken

Substitute the value we get

→ 800 = 900×4×t

→ 800 = 3600 ×t

→ t = 800/3600

→ t = 8/36

→ t = 2/9

→ t = 0.22 s

Therefore, the time is 0.22 Second .
