What is a series circuit?
Series circuits work when the circuit is electrified in three different paths. The metal coil wrapped around the wire making Series Circuit.
Series circuits are made when one or more electrical pathways are going to a coil making a circuit.
A series circuit is an electric circuit that has only one pathway for electric current to take. You can think of a series circuit as a set of parts that are connected end to end.
A Series circuit is a metal wire connecting all points of electricity making a circuit that is wrapped in a coil.
What happens to the voltage when it is dropped off
The voltage goes on and off
The voltage stays the same
There is more voltage
There is no more voltage
What are components
Only one force that keeps the the components together and equal to balance out the circuit, the circuit is one whole force.
Each of two or more forces, velocities, or other vectors acting in different directions which are together equivalent to a given vector.
When two or more vectors combined making a balanced circuit the circuit is equally charged by the vectors
When the forces don't connect nothing happens.
