So in other word the .4mm will require less voltage to operate than the .7mm.

Rep Power: 448 according to www.sparkplugs.com
Denso is claimed to have .4mm electrode size
NGK is claimed to have .7mm electrode size
if the Denso created less voltage to perform, would it create less spark also??

No. The sparkplug will require less voltage to create the same spark in a given gap.

Rep Power: 812 That's true. Running regular ngk vs iridium I saw a huge voltage requirement difference. The copper plugs dropped system voltage by almost .5V! Iridium is the way to go for lightly modded cars.
