Objects become positively or negatively charged due to electron transfer.
Electrons carry a negative charge.
The unit of electric charge is the coulomb (C).
The capacitor discharges, providing a momentary current.
The charge in the capacitor depletes quickly, causing a brief glow.
A capacitor provides a momentary flow, while a button cell provides a continuous flow.
It is the work done to move a unit charge between two points.
Emf is the potential difference when no current is drawn from a cell.
Using a voltmeter connected across the terminals of a cell.
The total emf equals the sum of the individual cell emfs.
The maximum potential difference is 6 V.
It is the quantity of electric charge flowing per unit time.
Current is calculated as charge divided by time (I = Q/t).
The unit is the ampere (A), equivalent to C/s.
Cells that cannot be reused after discharge, like dry cells.
Rechargeable cells that can be reused, like mobile batteries.
