Given,
V = 3V
I = 0.4 = 4/10 Amps
t = 5minutes = 5 x 60 = 300 seconds
E = ?

E = VIt = 3 x 0.4 x 300
                   OR
               3 x 4/10 x 300
This gives us the answer, i.e., E = 360J
Hope this helps.

Answer:

360 joule .

Explanation:

V = 3V

I = 0.4

t = 5 minutes

= 5 × 60

= 300 seconds

e = ?

Energy = V.l.t

= 3 × 0.4 × 300

360 joule
