a) coulomb is the SI unit of charge
b) I=Q/T
200000 amp = Q/ 1200 seconds
Q= 200000× 1200
240000000 coulomb of charge

Answer:

Coulomb is the SI unit of charge. It is equal to the quantity of electricity flown in one second by a current of one ampere.

The relationship between Electric current, charge, and time can be deduced from the definition of coulomb.

It is I = Q/T

Where, I denotes the current, Q denotes the charge and T is the time taken.

Putting the given values in above equation, we get;

200 * 10^-6 = Q / 20*60

2* 10^-4 = Q / 1200

Q = 1200 * 2 / 10000

Q = 0.24 Coulomb
