Capacitors

Electric fields in circuits
Electrons move round a circuit due to the force exerted on them by an electric field that is
set up within the conduction material.
However when there is a gap in the circuit, the electrons may be able to feel the force of
the electric…

The time constant tells you how long it takes
for the current to fall to 37% that of it's starting
value.
Charging the capacitor gives similar curves.





Discharging capacitor maths
The graphs above have a constantly changing
gradient which in itself does not change at a constant rate. They are…
