what is cause of static electricity? I experience shock
when i touch metal equipment in a room ,furher check shows
earth leakage showing 80ma at the DB near to the 400 MCCB?

Answer Posted / Dayan Singh

Static electricity occurs due to an imbalance of electrical charges within or on the surface of materials. When materials such as your body and metal equipment have different electrical potentials, electrons can be transferred from one object to another. This can cause a shock if the transfer of electrons results in a sudden discharge.nnThe earth leakage you mentioned is likely an indication that there is a ground fault in the electrical system, which could potentially increase the risk of electric shocks. The measurement of 80mA at the DB near to the 400 MCCB suggests that there might be a problem with the grounding or wiring.nnIt's recommended to consult with a qualified electrician to investigate and address any potential issues.

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
