Calculating amps used for low voltage lighting

[admin]

Can anyone explain how to calculate amps used on low voltage lighting.

For example. would 10 * 50 watt 12volt bulbs use the same amps as 5 * 100 watt 240 volt bulbs.

 

Thanks

Here is an online amperage chart that might help Dave.

Dave
formula is as follows

 

Current = Power/Volts

 

So:

10x( 50/12 ) = ~42A

5 x (100/240) = ~2A

 

So the obvious answer is no! but they will both cost almost the same to run, you will have some extra overhead for the ELV transformers.

Ray said:In both the voltage levels ie 12 V and 230 V. power consumption is same ie 500 watts. The Amps = W/V and styhus shall be 500/12 amps and 500/230 amps
