Question

What charge would be transferred if 20 micro amperes flows for 3 and 4 minutes?

Answer 1

Answer:

3 A = 3 Coulomb / sec.

5 minutes give 3 × 5 × 60 = 900 Coulombs is the charge flow through the circuit.

There cannot be net charge transfer since the system is charge neutral.

Answer 2

Answer:

Charge for 3 min will be 6×10^-5 C and for 4 min charge will be 8×10^-5 C

Explanation:

Apply the formula of Charge = Current × Time

1 micro amperes = 10^-6
