When electric current passes through the conductors, it increases:
Correct answer: B. K.E of the atoms
- A. P.E of the atoms
- B. K.E of the atoms
- C. Atomic size
- D. Number of protons
Explanation
When electric current passes through conductors, it primarily increases the kinetic energy (K.E) of the atoms in the conductor. This increase in kinetic energy is due to the collisions between the flowing electrons and the atoms in the conductor.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
