Question

How many coulomb of electricity will be consumed when 100 mA current passes through a solution of AgNO,
for half an hour during electrolysis?
(1) 108 C
(2) 180 C
(3) 1800 C
(4) 18000 C
​

Answer 1

Answer:

2.180 C

Explanation:

amount of current = C = 100 mA or 100/1000 A

time = t = 1/2hr or (1/2 x 60 x 60) sec

amount of electricity= Q = ?

Q = C x t

= (100/1000 A) x (1/2 x 60 x 60)

= 180 coulomb
