It Should be of value  4 Amp current rating and 12v voltage rating.

Swayam7710: solve it
jatin150415p9u9a0: Power rating=48w.Volatge is 12V
Power=V*I
48=12*I
I=48/12=4Amp
Swayam7710: but
Swayam7710: correct answer is 5A
jatin150415p9u9a0: Numerically my answer is correct but as per industrial standard ;Using the guideline that the fuse is rated at 125% of the normal operating current
We have to multiply 1.25 with 4, So the answer would be 4*1.25
I mean always multiply 1.25. At the end and here you got the answer 5Amp

Answer: 4 ampere

Explanation:  as we know that

power = voltage x current

therefore 48W  = 12V X A

               or A = 48W/12V

               OR A = 4 AMPERE
