Question

Which of the following are not the mobile charge carriers in a conductor?

• A. Electrons
• B. Protons
• C. Neutrons
• D. Deutrons

Answer 1

Answer: (B), (C), (D)

Deutrons

Electric current in a circuit is caused due to the flow of free electrons. Each electron carry a charge of approximately $-1.6\times {10}^{-19}C$. Protons also carry equal amount of charge but are not free to move. Hence. they are not the mobile charge carriers.
