Which of the following is an analogy for electrical current? (2021)
Step 1: Understand what electrical current is. It is the flow of electric charge in a circuit.
Step 2: Think about how water flows through a pipe. The movement of water represents something moving from one place to another.
Step 3: Compare the flow of electric charge to the flow of water. Just like water moves through a pipe, electric charge moves through wires.
Step 4: Realize that the amount of water flowing can be compared to the amount of electric charge flowing. More water means more flow, just like more electric charge means more current.
Step 5: Conclude that the analogy of water flow in a pipe is a good way to understand electrical current.
