How Do Circuits Work? Volts, Amps, Ohm's, and Watts Explained!

What is a circuit and how does it work? Even though most of us electricians think of ourselves as magicians, there is nothing really magical about electricity!! In the latest episode of Electrician U, Dustin explains the theories behind how a circuit actually works and the basic principles of electricity. 🤘⚡️EU Learning System⚡️🤘 For Individuals --- https://electricianu.com/learning-sys...

Volts, Amps, Watts, and Ohm’s (or resistance). Each one plays an important role in the flow of electrons within a conductor and can change how the overall experience is perceived. First let’s discuss volts. Volts relates to pressure. This PRESSURE is what moves things along. On one end of a circuit, somewhere, there is a generator that is creating this pressure. The other end (which we will discuss momentarily) is using that pressure to be useful. Voltage can come in several different amounts. The higher the voltage the more the pressure. 12 volts is much less than 120 volts, which is much less than 480 volts. The lower the voltage the more you risk not having enough pressure to operate a higher quantity of loads or go as far in distance. One reason we use higher voltages for those situations. What we are actually pushing with that pressure is current and that is measured in AMPERES (amps). Think of amps as flow. How much is actually going thru the circuit. So, amps can be thought of as how much is flowing thru the circuit per second. The smaller the amount, the less the amperage. Some equipment requires more amps to operate (motors, large light bulbs, etc.). Water can be a good analogy to use when discussing parts of electricity (even though the two REALLY shouldn’t be put together!!). While water pressure could be used to describe VOLTS, the flow rate (or gallons/liters per minute) can be used to describe AMPERAGE. The next part of the puzzle is resistance. If we were to hook up a wire straight in between a hot and a neutral, there would be an infinite amount of current allowed to flow as there is no resistance to slow it down. This would end in a rather catastrophic event! So, resistance slows down the rate of current flow to a more manageable/useful rate. Remember, for a circuit to work, it must be a complete loop. So a resistive load completes the loop enough for current flow to slow down to a useful rate, but not great enough to create a short circuit! Take a light bulb for instance. One side of the lamp is connected to one end of a filament while the other side is connected to the other. When power is applied, the filament glows, slowing down the rate of current flow but completing the circuit. The last part to discuss is wattage. Think of wattage as power consumption. How much work is being performed. Take a toaster for example. We need wattage to toast our bread. The resistive elements get hot from current flow/resistance. That power consumption is measured in watts. The higher the watts for our toaster, the hotter it will get and faster it will toast our bread.
