Experiment 5 - The Capacity

Replace in the circuit from the last experiment the capacitor C1 by a through a 10 μF capacitor. Observe the difference from the last experiment ...

  • The LED1 lights up significantly shorter while charging.
  • The LED2 also lights up significantly shorter when discharging .

A 10 μF capacitor stores less electrical energy than a capacitor with 100 μF.

Circuit with electrolytic capacitor. (Enlarge)

What is meanst by a capacity of 1 Farad?


A 1 farad capacitor, charged at a voltage of 1 volt, provides a current of 1 ampere for 1 second.

You might be wondering whether this is much or little. In the next experiment you compare a capacitor with a battery.
