Answer: B superconductors
Explanation:
In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component. If two or more components are connected in parallel they have the same potential difference ( voltage) across their ends.
Answer:
Free electrons in a conductor
Explanation:
Current in a conductor is due to flow or motion of the free electrons in it.
The electric current is the flow of electrons in a conductor. The force that causes the current flow through a conductor is called the voltage.
