1, what is supply voltage for core 2 duo & dual core & other procesosor.
2. What is normal operating current.
3. They are CISC or RISC

Intel's website lists the VID voltage range as part of the specs for every CPU, the amounts vary but are usually between 1 and 1.3 volts. CPU's can be run slightly outside the range, but at the risk of stability (if undervolted) or excessive heating (if overvolted). Intel doesn't (as far as I know) publish current draw, thought they do publish max TDP (thermal design power). This represents the amount of power the computer's cooling systems must dissipate from the CPU and isn't an absolute limit on how much power the CPU can draw. Taking the Core 2 Duo T7500 as an example, it has a VID voltage range of 1.075 - 1.250V and a max TDP of 35W, which would represent a current draw of 28 - 32.6 amperes.

As far as RISC and CISC, that terminology is rarely used these days. Intel CPU's certainly descend from the CISC tradition, but over the past few decades there has been convergent evolution between the two worlds and it would be fair to say that modern CPU's are all RISC/CISC hybrids.
