Category: 3. Electrical Voltage

Batteries are sources of Direct Voltage meaning the pressure it provides moves the electrons in a constant current in one direction, like the flow of water down a river. Direct voltage is usually represented with a capital V with some dots above it and a small horizontal line. If we plotted this voltage against time,… Continue reading AC and DC Voltages

We measure the potential difference or voltage with the unit of Volts and we use the symbol of capital V to show this. If you look on your electrical appliances you will see a number next to a V, indicating how many volts the product is designed for. In this example the manufacturers of this usb hard… Continue reading Voltage Labels

If we connect a piece of wire to both terminals of a battery then the pressure of the battery will force the electrons to flow in the same direction along the same path. We can then place electrical components in the path of these electrons to do work for us, for example we place a… Continue reading Voltages Connected With Piece 

Electrical voltage basics. In this video we’re going to be discussing voltage, we’ll learn what is voltage and potential difference, how to measure voltage, the difference between direct and alternating voltage and current as well at why voltages vary around the world. Voltage is what pushes electrons around a circuit. Without voltage the free electrons… Continue reading Voltage Basics
