Understanding Amps and Volts

Before we explore the amp draw of a 12-volt water pump, let’s first understand the concepts of amps and volts.

Amps, or amperes, measure the current flow in an electrical circuit. It indicates the number of electrons passing through a point in a circuit per second. Amps are essential because they determine the amount of power consumed or delivered by a device.

Volts, on the other hand, measure the electrical force that pushes the current through a circuit. It represents the potential difference between two points in a circuit and determines how much work the electricity can do. In the case of a 12-volt water pump, it requires a 12-volt power supply to operate efficiently.

To put it simply, amps represent the quantity of electricity flowing, while volts indicate the force or pressure of that electricity. Think of it as a water pipe analogy: amps would be the volume of water flowing through the pipe, and volts would be the water pressure pushing that flow.

In an electrical circuit, the relationship between amps, volts, and power, measured in watts, can be calculated using Ohm’s Law. Ohm’s Law states that the current (amps) flowing through a circuit is equal to the voltage (volts) divided by the resistance (ohms) of the circuit.
