Can someone use a good analogy to explain the difference between voltage and current?
i.e. Difference betweens Volts and Ampers.

i read wiki but i still want a better understanding...


and what's a resistor do? does it just suck power up into nothingness? like a drain or spong? thx

The three most basic units in electricity are voltage (V), current (I) and resistance (r). Voltage is measured in volts, current is measured in amps and resistance is measured in ohms.

A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size.

volage is the size of the elefant
amperage is the number of elefants stampeding towards you

electricity 101:
Voltage is 'supply' and ampheres are the current.
Visualize this:
A water tank has a pipe coming out the bottom of it with a valve at the bottom of that pipe.
The water wants to find the closest path of least resistance to the ground, which is through that pipe. The amount of water in the tank and the size of the pipe combined with the amount the valve is opened, determines how much water gets on the ground and how fast it gets there. Now put a bucket under the stream of water....when it fills up, the water spills out and continues to go on the ground.

Now let's transfer those principals over to electricity:
*amount of water in the tank (supply) = voltage
*size of the pipe coming out the tank = conductor
*amount the valve is open = resistance
*how fast the water is allowed to go through the pipe = amperage (current)
*how big the bucket is between the valve and the ground = capacitance
*how much work that the falling water does after being manipulated (if used to
power something EI: waterwheels, turbines etc.) = wattage


PS: it's more the ampherage that kills you and not so much the volts.

i figure you could use jiz some how

[Cartman]

Thank you all very much

Volts jolt and amps kill

[Jackalope]

volts can still kill you.

[PapaBigFace]

1,000,000,000 volts with no amps cannot kill you

Hurt like a mother, yes, kill no
