i have a 2.5kva 230/115volt 50Hz transformer. i want to measure inductance of its primary and secondary windings. without an LCR meter how i can perform this task?
thanks
ac circuits::
impedence:
total opposition in flow of current in a circuit.
Z= V/I
Resistance:
real component of impedence. it is situated at zero degree from applied voltage.
when you creat high potetential difference between very small air gap, air in the gap becomes ionize and began to pass electricity.
same happens when you switch on or off a circuit it begins to conduct before formation of intimate contact and passes current according to power of...
how i can build surge suppression circuit with minimum response time and maximum energy dissipation using "metal oxide varistors"
OR
plz give other suggessions and websites,
thanks
i want to connect an over under voltage shut down circuit at 3-phase input mains.
input power supply specs are following:
400V 50Hz delta .
have you any circuit or web link for this purpose.
thanks
when a current more than 0.5ma passes through human body there is a threshold of perception.
shock is only dependent on current passing through the body.
man can stay alive even after 20kv shock if power behind these voltages is too much small. STUN...
