The slope-of the charge-time graph for a charging capacitor gives:
Correct answer: A. Current
- A. Current
- B. Voltage
- C. Force
- D. Energy
Explanation
The correct answer is Current, as the slope of the charge-time graph indicates how quickly charge is flowing into the capacitor, which is defined as current (I = dq/dt). A steeper slope corresponds to a higher current, meaning more charge is accumulating over time. The other options do not represent this relationship: Voltage is related to the charge stored but not the rate of charge flow, Force is unrelated to charge and time, and Energy pertains to the work done to charge the capacitor rather than the rate of charge accumulation.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
