thanks for your reply. i have gone through the above link. in that they are telling the reason of voltage drops in transmission and distribuition lines. i think you haven't understood my question. ok.. so, in every transmission and distribution lines there would be certain drops, reason may...

yeah, in this it is written:" if you add an extra element, the other elements will still have the same amount of voltage as before. If you remove an element, the other elements will also still have the same amount of voltage as before" so why there is voltage fluctuation?? there should be...

ohkay. i have seen a avoltage stabilizer attached to my computer. i was told it is to remove any voltage fluctuation occurring in supply. but, my query is...why voltage fluctuation will occur and not current fluctuation?

why voltage fluctuation is there? since all the houses are in parallel,so all of them receive same voltage..then why voltage fluctuation is there? and why not current fluctuation? why voltage stabilizers are used ?

what will happen if I ground my 12v(low voltage system) and 144v(high voltage system) to a common ground?

5T is the time for current to reduce to a manageable value. and you are saying correct that it will come 74.45 sec,but since our application is electric vehicle,it is practicaly impossible to wait for that much time before vehicle can start.so, I am apprehensive about it.

i have calculated time constant using formula 5T=R*C, and it is coming 2.97 sec! but when i am plotting the graph of voltage versus time using formula v= 1-e^(-t/rc) graph is coming linear instead of exponential. where m i going wrong? i have also used the formula v=e0(1-e^(-t/rc)), from this...

please help me with plotting of graph between "current versus time" for precharge resistor- 2.2 kΩ 20W. this is placed across a contactor,which is linked to a motor controller with capacitors of value:6768μF. closing time of resistor is calculated as 2.97 sec!

circuit diagram this the circuit diagram.please refer and help me how to discharge the capacitors in controller

we are designing a electric car. in that motor controller has capacitors which get charged when supply is given.so across the contactor we are attaching a precharge resistor,which prevents the hiigh inrush of current in motor controller. now we are stuck on the ques that how to discharge the...
