1 - Component
The electric resistor is a dipole composed of a conductive material which opposes the passage of electric current.
3 - Allocation table
Resistors heat up when an electric current passes through them. They are of different powers to dissipate calories.
3- Resistors in series
Using a multimeter calibrated on Ohm, the equivalent resistance taken at the terminals of the resistors connected in series is added.
4 - Resistors of the same value online
5 - Resistors of different value online
Using a multimeter calibrated on Ohm, the equivalent resistance taken across the terminals of the resistors of different ohmic value connected in parallel is lower than the lowest resistance.
