The electric current in a series circuit
In a series circuit the current remains unchanged all along the
circuit: all electric components receive the same current.
In the following circuit, the electric current leaves the positive
terminal, flows through the bulb, flows through the resistor and then
reches the negative terminal
All along its
path the current remain the same thus we can write:
Current and number of passive components in a circuit
I1 = I2 = 3
In series circuit electric, current decreases if a passive component is
The more passive components a series circuit includes, the more current
Inversely, if a passive component is taken off from a series circuit
then electric current increases.
Current and order of connection
Whatever is the order of connection in a series circuit, the current
These three circuits all include an electric generator, a motor, a
bulb, a resistor, an ammeter and five connection wires. The only
difference between these circuits is the way components are connected.
We can therefore deduce that the current is the same in all circuit:
I1 = I2 = I3
