I have three leads.

1 is 1.75 - 2 VDC

1 is 1.75 - 2 VDC

1 Is Ground

I need 3 VDC to power a simple laser so my question is does electricity run concurrent or consecutive. In other words if I joined my two 1.75 leads together would I have 3.5 or 1.75 VDC?

Logic tells me that I would have 3.5 so I would then need a resistor to smooth out the voltage to a steady 3VDC???

However the specs say: "operating range 2.8-5VDC" so I won't need a resistor??

The specs also say: "Current consumption is 7ma at 3.2VDC"

So again I am new to this field so just running with logic I take that to mean that the laser will consume 7ma at 3.2VDC and a higher input voltage will consume more amps off your total circuit.

Thanks for the help

If it matters here is the laser I got.
