Voltage
Voltage in electronics is simply the potential energy difference between two different points of measurement. In most scenarios, you will find the reference point taken to measure the voltage of a given point is ground (GND), or the negative terminal of a battery or power supply. To put this in a real-life context, if you have used a 9V battery, this means that the potential difference between the two points would be 9 volts.
To go on to a deeper level, let's say that at the two ends of a conductor, such as copper wire, you have a huge amount of electrons (negative charge) and at the other end you have protons (positive charge). This means that there is a difference between the potentials of these two points ultimately leading to ...
