Final answer:
The colored bands of a resistor are arranged and read closest to the power supply circuits. These bands indicate the resistance value of the resistor.
Step-by-step explanation:
The colored bands of a resistor are arranged and read closest to the power supply circuits. The colored bands on a resistor are used to indicate the resistance value of the resistor. This information is important when designing and building circuits, as it helps to determine the amount of current that will flow through the resistor.
For example, a resistor with a lower resistance value will allow more current to flow through it, while a resistor with a higher resistance value will allow less current to flow through it.
