In electronics it is customary to define the potential of ground (thinking of the Earth as a large conductor) as zero. Is this consistent with the fact that the Earth has a net electric charge that is not zero?
Really? Do you have a reference for what the net charge on the Earth is?sami23 said:the Earth has a net electric charge that is not zero

Potential ground, also known as earth potential or ground potential, is the voltage level at a particular point on the earth's surface. It is used as a reference point for measuring electrical potential differences.
Potential ground is established by connecting an electrical conductor to the ground, such as a metal rod or a wire, and then connecting that conductor to an electrical circuit or system. This allows excess electrical charge to flow into the ground and maintain a neutral potential.
Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. It is measured in units of coulombs and can be either positive or negative.
The two types of electric charge are positive and negative. Positive charge is associated with protons, while negative charge is associated with electrons. Like charges repel each other, while opposite charges attract.
Electric charge can affect potential ground by either raising or lowering its voltage level. For example, if a large amount of electric charge is added to the ground, it can increase the potential ground level and create a hazard for nearby objects or people. By contrast, if electric charge is removed from the ground, it can lower the potential ground level and potentially cause electrical equipment to malfunction.
