But what you may not know is that the light flashes because of an RC circuit!
The duration of the flash is determined by the resistance and the capacitance in that circuit.
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).
Of course, circuits can be more complicated than these two basic types.
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.One such type of circuit is an RC circuit, which is a circuit that has both a resistor and a capacitor.This is exactly where the 'R' and the 'C' in the name come from.I In any parallel circuit of elemnts: R, C,: resistance, capacitance (and or inductance) , the voltage across all 2 elements is the same, the current through individual elemnnts and its phase differs.Since the voltage is the common factor, the vector diagram will have the 2 currents relative to the voltage reference vector.As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.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.For example, a small capacitance would produce a quicker flash, whereas a larger capacitance would produce a slower flash.But we're getting ahead of ourselves, so let's back up for a minute and go over a few more details of the circuit itself. The circuit has a battery, a capacitor, a resistor, and a switch that opens and closes the circuit.
