And just like the names imply, a series circuit connects devices in series (like a string of Christmas tree lights), and a parallel circuit connects devices in parallel (like the outlets in your house).

Similar to a battery, a capacitor has two terminals and stores electrical energy.
When a capacitor is connected to a battery in a circuit, the electrons flow from the battery to the capacitor plate that is connected to the battery's negative terminal.
We call the rate of decay of current and voltage the time of decay.
This value is represented by the constant τ, which is equal to R*C and is measured in seconds.
This makes sense because voltage produces current, and resistance, well, resists it.
OK, now that you know what an RC circuit is made of, let's get to the good stuff - the circuit itself.In an electrical circuit, a resistor passively opposes the flow of current.In other words, it 'resists' the electron flow moving through the circuit.In order to better understand RC circuits, we first need to know more about the two components that define it.A capacitor is two parallel plates separated by an insulator.Touch screens on modern smartphones and tablets also employ capacitors, making them quite useful!The other important part of an RC circuit is the 'R' - the resistor.Capacitors are useful because they can get rid of their charge much faster than a battery can.This makes them good for things like a camera flash that needs to use that charge very quickly.When the switch is open there is no current flowing through the circuit so the capacitor does not discharge to the resistor.If we close the switch and complete the circuit, this allows current to flow and the capacitor to discharge through the resistor.
