An electric device is rated 2000W, 250V. Calculate the maximum current it can take
9A
8A
7A
6A
Correct answer is B
I = \(\frac{P}{v}\)
I = \(\frac{2000}{250}\)
I = 8A
N90
N50
N45
N5
Correct answer is C
P = 40 x 10 + 100 x 5
P = 400 + 500 = 900W
Cost = \(\frac{900 \times 10 \times 5}{1000}\)
Cost = N45
