N-Type Gates vs. P-Type Gates

Gates are a fundamental part of creating useful circuits.  These gates either allow or block voltage from flowing through them based on the input given them.   I won’t go into what makes each type of gate work, but I will detail how they work and ways to manipulate them to your will.

N-Type

N-Type gates are normally open, meaning no electricity gets through them.  When the gate is given a voltage, then the gate becomes closed (as in closing the circuit) and thus acts like a piece of wire, allowing voltage to flow freely.

P-Type

P-Type gates are complimentary to N-Type gates in that they perform the exact opposite function.  These gates are normally closed, meaning a P-Type gate acts like a piece of wire when supplied with 0 volts.  Giving the gate a voltage will cause it to be open, breaking the circuit and blocking energy flow.
