Potential Diff b/w 2point is called Voltage,the flow of
electron is called Current where it flow from High potential
to Low potential.

Simply says, Voltage is "Pressure" i,e.,Potential Difference
and Current is "Flow" i,e.,Flow of electrons.

Answer / ajit

current is the measure of flow of ellectrons.
voltage is the potential differnce between the two points.

Answer / gg

CURRENT MEANS FLOW OF ELECTRONES IN CLOSED PATH $ THE FORCE
IS REQUIRE TO MOVE ELECTRONES THAT IS CALLED VOLTAGE, THAT
MEAN CURRENT IS FLOW BUT VOLTAG NOT FLOW.

Answer / varun kumar

volage is a phenomenon & current is a effect of that
phenomenon.current is flow due to volage but volage is not
due to current. if circuit is open then current is zero in
that circuit but voltage is not zero.

Answer / abhay

We Can Measure Current in single phase,but For measuring
voltage 2 Phase are required(1 may neutral)

how much current capacity 250 amp. mccb please tell me about whats are the reasons to trip 2 or 3 times in a night. and what are the steps to short out this problem

Energy metering: On the property I am renting, the supply voltage is 2 x 110 volts. These 2 x phases enter a energy meter which then exit the meter to over head lines to my house. Question 1. The meter is single phase 240 volts but is being used as 2 x phase(2 x 110volt), is this acceptable? if not, please give me the reasons. The meter details are as follows: 60Hz 15amp Imax 100 amp Kd 3,6 Wh/R 1 fase 3 hilos Model FX 231. I think it was manufactured in Brasil From this meter, the cables run along over head aluminum conductors,I estimate the cross sectional area to be 25mm diameter, but the neutral is only about 10mm square diameter, which cover a distance of 170 meters and then terminate with an underground cable of 65 meter length, total length = 235 meters. There must be a huge voltage drop over this length. This line is protected with 2 x 200 amp aluminum fuses after the meter, there is no main switch in the distribution board. These 2 phases connect directly onto 2 busbars. Surely the neutral should be the same size as the conductors if not more? Question2. What are your thoughts about this installation, should there be better protection, is the neutral too small? During the night, the lights dim then brighten all the time, this cannot be good for my electrical appliances. In my home, I only have a small electric geyser and fridge, my stove works off gas. But when i use other appliances like the washing machine or microwave oven, the light dim. The internal wiring of this house is done with solid hard drawn copper wires and of course, they have to be under rated. I am a retired electrician by trade, but not on the metering and over head mains side, my experience is on the factory maintenance side of things. Your expertise on these matters will be greatly appreciated. Please inform me how to rectify or make any improvements Kind regards, my power bill is very expensive, so I need to know how to bring it lower. Kind regards, Brian
