insulation resistance can be measured by means of megger, with built in d.c generator. It is measured between the conductor and the earth. earth resistance can be measured by means of earth resistance tester. For good effective earthing, th earth resistance should be of order 0.5 ohm
what is the resistance value of a healthy earth pit
Rm= 8Mp/L
Earth pits for grounding purposes should be located far apart to prevent them from interfering with each other's effectiveness. Placing them too close can result in shared ground resistance, reducing the efficiency of the grounding system. By spacing earth pits adequately, you can ensure each pit functions optimally and mitigates potential electrical hazards effectively.
If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.
The maximum resistance across a switch should be infinite.

We use earth pits for by-passing the high voltages from the lightning rod in case of thunder strikes.. After digging earth pits, salt(na-cl) & charcoal.....salt increases conductivity, whereas charcoal decreases conductivity......so we use charcoal
4'X3' pits and distance is 40' from stake to stake

An object falling towards the Earth will stop accelerating once it reaches its terminal velocity, which is the maximum speed it can achieve due to air resistance. This happens when the force of air resistance is equal to the force of gravity acting on the object.

The maximum voltage formula for a circuit is V I R, where V is the voltage, I is the current, and R is the resistance.
