Resistance is the measure of a material’s ability to conduct electricity. The lowe r the resistance, the better the material conducts electricity. When earthing, we want to use materials with low resistance so that the electrical current can flow freely from the ground to the earthing system.
There are two ways to achieve low resistance in electrical earthing: by using conductive materials or by bonding the earthing system to the ground. Conductive materials, such as copper or aluminum, have low resistance and can be used to create an earthing system. Bonding the earthing system to the ground also creates a low resistance path for the electrical current to follow.
The most important thing to remember when choosing a material for electrical earthing is to choose a material with low resistance. This will ensure that the electrical current can flow freely from the ground to the earthing system.
