Question

potential drop = 24 V
current = 3A
time= 50 hrs
energy=?

Answer 1

V=24V

I=3A

t=50hrs

E=V×i×t

=24×3×50

=3.6Kwh

hope it helps you frnd

Answer 2

Answer:

Energy = 12,960,000 J

Explanation:

According to the given question,

Potential drop = 24 V

Current = 3 A

Time = 50 hrs = 50 × 3600 s

(1 hr = 60 min = 60 × 60 sec)

And we are asked to find Energy,

We know Energy = I^2Rt

• I = current

• R = Resistance

• t = time

So, we have to find the value of resistance first and for that.

From Ohm's law,

• V = IR

where V = Potential

So, 24 = 3× R

• R = 8 ohm

Therefore, Energy = I^2R t

(E = Energy )

So, putting the values

• E = 9 × 8 × 50 × 3600 Joule

• E = 12,960,000 J ans.
