Topic :: Resistance
An engineer measures the direct current resistance of a transformer using ohm meter. When he/she takes out one of the leads of the meter, spark comes.. Why ?? This effect is known as...
1 9234what is the min and max ohmic resistance for the earthing rod installed for lighting poles for street light network
1 3695In a 2 stage RC coupled amplifier, the emitter resistance of 1st stage consists of 2 resistances (Re and Re')in series and the bypass capacitor is connected across only one of them(bigger resistance). Why?
2803We have two 1 phase heating coils having same resistance of 25ohm, but during operation one takes 3A and other 6A Is it posiible Pls. explain
Bhel,
5 6673How do we calculate the resistance per metre of single core aluminium stranded cable 19*3.25mm sheathed in pvc,at 15 deg C temperature?
2348resistance is the property of a material to resist the flow of current... now by ohm's law current is directly proportional to voltage. then why we transformer in small appplication... if we use resistance in daily life it will be more sufficent,cheaper,etc. than transformer

Why Transformer Neutral having one earth pit ( more earth electrode resistance) whereas body have many earth pit ( less earth electrode resistance)?
which are the criterias needed to select the kind of neutral earthing(solid earthing,resistance earthing,etc.) at various voltage levels in electrical distribution?
exactly how does an RTD 3 wire or 4 wire device cancel out the resistance of the wires , opposed to a 2 wire RTD? Is it because you have resistors in parallel , or because something to do with the electronic circuit the RTD is connected to ?
I have 4 DG set with 1500KVA rating. system breakers are 11KV & alternator are 415 Volts. Between alternator & breaker one stepup transformer used. i want to Know what is max. resistance for body earthing & 415 & 11KV V Neuteal earthing. my fault current is 14 times for 2 sec.
