What are amps, watts, volts and ohms?
The three most basic units in electricity are voltage (V), current (I, uppercase “i”) and resistance (r). Voltage is measured in volts, current is measured in amps and resistance is measured in ohms. A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size. There is a basic equation in electrical engineering that states how the three terms relate. It says that the current is equal to the voltage divided by the resistance. I = V/r Let’s see how this relation applies to the plumbing system. Let’s say you have a tank of pressurized water connected to a hose that you are u
