Energy Delivered Cell
Mediumphysics
Energy delivered by cell with EMF E and charge Q passed is:
Select the correct option:
Solution
Incorrect! Answer:
E Q
Work (Energy) is defined in terms of charge (Q) and potential difference (V or E): W=E×Q
- This corresponds to the power formula P=E×I integrated over time (E∫Idt=EQ).
- This total energy is split between the external circuit and the internal resistance of the cell.
