A type of circuit where all devices are connected one after the other, when one element is off the rest are turned off as well.
What is a series circuit?
400
Devices that either “step-up” increase voltage or “step-down” decrease voltage.
What are Transformers?
500
A type of material that will allow static charge to build up over its surface.
