LED
LEDs or light emitting diodes, unlike resistors, are polarized. They have an anode (positive) and a cathode (negative). The longer lead is the anode and the shorter one is the cathode.
Different colors of LEDs have different current capacities and need appropriate resistors connected to them when designing a circuit.
Resistor
Resistors are used for limiting the current flow through a circuit. The resistance values of resistors can be checked by looking at the coloured bands on the body of a resistor.
Resistors are not polarised, meaning you can connect the positive or negative terminals of the battery to either lead of the resistor.
Battery
Batteries are essential power sources in electronics, providing direct current (DC) for circuits. They consist of a positive terminal and a negative terminal. It's important to note the correct polarity when connecting batteries to a circuit.
Various sizes and types of batteries offer different voltage and current outputs for specific electronic applications.
Breadboard
A breadboard is a prototyping tool used in electronics to build and test circuits without making any permanent joints (soldering). It consists of a plastic board with rows of interconnected metal sockets. Components are inserted into these sockets to create electrical connections. Breadboards allow for quick and temporary circuit assembly, making it easy to experiment and modify designs before finalising them on a more permanent circuit board.
