Question

What is the direction of flow of current inside a dry cell?

• A. from $+$ve to $-$ve terminal
• B. from $-$ve to $+$ve terminal
• C. from $+$ve to $+$ve terminal
• D. from $-$ve to $-$ve terminal

Answer 1

The correct option is B from $-$ve to $+$ve terminal

The dry cell consists of a zinc can, electrolyte paste, and a carbon rod in the center. A chemical reaction takes place between the zinc can and the paste. Electrons flow from the negative (zinc) terminal to the positive (carbon) terminal. Electrons are then pumped back to the negative terminal.
