ELI5: Why electronics need resistors?

Why are resistors used in electronics?
gpt
People here are failing to address the main issue - explaining resistors assuming everyone already knows everything about a circuit.

Imagine a circuit like a bunch of pipes with water flowing. The water pressure is voltage, and the current is the amount of water flowing through. Now imagine you have something which is powered by water, let’s say a garden hose. When you connect the garden hose, you don’t want the water flying out at a crazy high pressure. It could hurt you, and damage things. This is the same in circuits. The components in the circuit can’t all handle the high voltage, just like how your hose can’t handle the high pressure. So what’s done to fix this? You add a valve to the hose, or a resistor to the circuit. The valve on the pipe will restrict the amount of water that can flow through - protecting whatever the water is being used for. Just like this, a resistor is used in a circuit to protect components that could be damaged otherwise.

Of course, there are a lot more applications of resistors. However, protecting components is a common and simple use of resistors.
