What is the quantity of electricity produced when a current of 0.5A is passed for 5 hours 45 mins? (1F = 96500C)
-
0. 11F
- 0.12F
- 0.22F
- 1.1F
- 2.2F
The correct answer is: A
Explanation
Given:
Current, I = 0.5 A , t = 5 hours 45 mins = (5 x 60 x 60) + (45 x 60) = 20,700 seconds ( Time must be converted to the standard unit which is second)
Also, recall that Q = It = 0.5 x 20,700 = 10,350C
Thus, if 1F = 96,500C
X = 10,350C
X = \(\frac{10,350}{96,500}\)
X = 0.107
X = 0.11F
