The lower part of a cloud has positive, The cloud discharges in flash of lightening, in which direction do electrons and conventional current flow:
Correct answer: C. Electrons: downwards, conventional current: upwards
- A. Electrons: downwards, conventional current: downwards
- B. Electrons: upwards, conventional current: downwards
- C. Electrons: downwards, conventional current: upwards
- D. Electrons: upwards, conventional current: upwards
Explanation
In a lightning flash, the lower part of the cloud becomes negatively charged. Electrons (which are negatively charged) move downward from the cloud to the ground, creating a path for the discharge. The conventional current, however, is considered to flow in the opposite direction of the electron flow. So, from the ground perspective, it appears as if conventional current is moving upward.

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.
