    who glow the bulb current or voltage?why?
    My qustion is
    if there are one colsed circuit one battery and a lamp,then If the voltage to lamp is zero v=0 and current is some value greater than zero. Will the lamp glow? And in other case I=o and v= >0 will the lamp glow. In which case lamp will glow and why?

    If the voltage = zero (0) then there is no amperage (0) and nothing will glow.

    Think about it! If you have (0) voltage, you have a dead circuit.

    This is just like the question.. WHAT KILL'S? THE CURRENT OR THE VOLTAGE?

    That's an easy one. Current (coulombs/s) kills. Voltage is just like pressure.
    It's about 10 mA across the heart muscle. You can't quantify voltage because of conditions like standing in a puddle, dry skin etc. To get that 10 mA, the voltage will vary all over the place.

    Take an other example. Water. Specifically a water jet cutter.

    Water won't harm you, right? You can drink as much as you want, right? Too much water and you drown. That's harm enough.

    Now say you put you hand under a water jet cutter. The water is now capable of penetrating the skin because it's entering at a very fast fate.
