Describing Circuits

All simple circuits contain a source of electric energy, an electric device, and an electric insulator.

In a series circuit, all components are connected to the electric source with a separate path, or branch.

Houses do not use series circuits. Instead, they use series circuits.

Breaking, or opening, a series circuit causes the electric current to stop flowing through the entire circuit.

In a parallel circuit, opening one branch causes the electric current to stop flowing through the entire circuit.

What is Resistance 2 value in a series circuit if Resistance total = 80 Ohm, Resistance 1 = 30 Ohm, and Resistance 3 = 20 Ohm?

In a series circuit Resistance Toal = 1 / (1/R1 + 1/R2 + 1/R3)

In a parallel circuit Resistance Toal = 1 / (1/R1 + 1/R2 + 1/R3)

In a parallel circuit Voltage Toal = V1 = V2 = V3

In a series circuit Current Toal = Current 1 + Current 2 + Current 3.

To find Voltage, V = I * R

Total resistance in a parallel circuit is always less than any of the branch resistances.

The advantage of of having a parallel circuit is to ensure all components in the circuit have the same voltage as the source.

To find Current, I = V * R

In a series circuit, current will be the same all throughout the circuit.

To find Resistance Total in a series circuit, R Total = R1 + R2 + R3.
