Ac -alternating current. it is sinusoidal. It has zero crossing point.
Consider house voltage of 230v/50hz. whether current (or voltage) in the positive half cycle is only able to glow light or current(or voltage) in the negative half cycle also able to glow light.
50hz - 50 cycles per sec. Tell me only because of this speed (50hz) light is continues. Tell me if 10hz-10cycles per sec is given what happen to light. whether it flickers....

I think because of zero crossing point we can escape in ac.
Tell me where the current or (voltage) willl be zero(at +ve half cycle or-ve half cycle)

#4 Bare Copper Solid

I am trying to obtain conversion factors so I can calculate how much actual copper is being purchased when a certain footage of finished wire is purchased. Thus, I need to get just the copper weight excluding plastic sheathing or any other items added in the manufacturing process.

Thanks for your help.

What is the difference between zero order reaction and pseudo-zero order reaction?

2006-06-14 03:00:09 · 2 answers · asked by Anonymous in Chemistry

I know generally with a larger population, a city is the largest. But I am not sure if the difference is just a legal one (how the town charter is written up?). Anyway, just looking to clarify this question that's been bugging me.

what is positive and what is negative?
whether positive carries positive current?,negative carries negative current.?
Then What is positive current what is negative current?
whether if we touch positive current what happen?
whether if we touch negative current what happen?
