What is a resistor on a bug zapper?

A resistor is an Electrical component that is uses to divide current and voltage up. They are used to make sure a certain component (for example an LED) gets the correct amount of current and voltage to preform efficently. Resistors have more uses than the ones I have just described, one more example is they can make the timing of a timer change. If u put a bigger resistor then the time delay goes up ect.
