An electric current of 100 mA is passed through an electrolyte for 2 h

1.	An electric current of 100 mA is passed through an electrolyte for 2 hours, 20 minutes and 20 seconds. Find the quantity of electricity passed.
Answer» Given : Electric current = I = 100 mA = 100 × 10^-3A = 0.1 A Time = t = 2 hrs + 20 min + 20 s = 2 × 60 × 60 + 20 × 60 + 20 = 8420 s The quantity of electricity = Q = ? Q = I × t = 0.1 × 8420 = 842 C ∴ Quantity of electricity passed, Q = 842 C

An electric current of 100 mA is passed through an electrolyte for 2 hours, 20 minutes and 20 seconds. Find the quantity of electricity passed.

Answer»

Given :

Electric current = I = 100 mA

= 100 × 10^-3A

= 0.1 A

Time = t = 2 hrs + 20 min + 20 s

= 2 × 60 × 60 + 20 × 60 + 20

= 8420 s

The quantity of electricity = Q = ?

Q = I × t

= 0.1 × 8420

= 842 C

∴ Quantity of electricity passed,

Q = 842 C
