1. Answer :-

   Value of current in the conductor is 4.8 × 10²⁶ A .

   Explanation :-

   We have :-

   → Number of electrons = 6 × 10⁴⁶

   → Time taken = 20 s

   → Charge of an electron = 1.6 × 10⁻¹⁹ C

   ________________________________

   Firstly, let’s calculate the total charge carried by 6 × 10⁴⁶ electrons :-

   ⇒ Q = 6 × 10⁴⁶ × 1.6 × 10⁻¹⁹

   ⇒ Q = 9.6 × 10⁴⁶⁻¹⁹

   ⇒ Q = 9.6 × 10²⁷ C

   ________________________________

   Now, we know that :-

   I = Q/t

   Substituting values, we get :-

   ⇒ I = 9.6 × 10²⁷/20

   ⇒ I = 0.48 × 10²⁷

   ⇒ I = 4.8 × 10²⁶ A

2. Answer:

   Given :–

   A total of 6 × 10⁴⁶;electrons follow through a current carrying conductor when connected through external power supply for 20s

   To Find :–

   Current

   Solution :–

   We know that

   Charge = Charge of one electron × Number of electrons

   Charge = 1.6 × 10-¹⁹ × 6 × 10⁴⁶

   Charge = (1.6 × 6) × (10⁴⁶ – ¹⁹)

   Charge = 9.26 × 10²⁷

   Now

   Current = Charge/Time

   Current = 9.26 × 10²⁷/20

   Current = 0.48 × 10²⁷ A
