Current Imbalance: GFCIs continuously monitor the current flowing in the "hot" (live) wire and compare it to the current returning in the "neutral" wire. If there is a difference of as little as 4-6 milliamperes (mA) between these currents, indicating that some current is not returning through the normal circuit path, the GFCI will trip and disconnect the power.
Leakage to Ground: GFCIs are designed to detect any unintended flow of electricity to ground, which could be potentially hazardous. This can occur when there's a fault in an electrical device, damaged wiring, or when someone comes into contact with a live wire or conducts electricity to the ground.
Rapid Response: GFCIs are engineered to respond quickly, typically tripping within milliseconds when they detect a ground fault. This rapid response helps prevent electric shocks and electrical fires.

Gfci circuitry checks for differences in current between the?
...hot and neutral conductors. (Sounds a lot like a homework question. If so, spend a little more time reading the textbook!)
Do you need a gfci outlet if you have a gfci breaker?
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
Can a circuit with a GFCI be shared at the box?
Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.
Are gfci plugs required in a bathroom?
Deoends on code you are governed by. In USA, a GFCI outlet or a circuit controlled by a GFCI circuit breaker would be required.

GFCI circuitry often checks for a difference in current between the ground and neutral?
A GFCI monitors the current in the ungrounded (hot) conductor and the grounded (neutral) conductor. If there is more than 6mA of current difference between the two the GFCI will open the circuit.

Can you use a GFCI plug into a GFCI outlet?
Yes you can. Lots of blow dryers have GFCI protection built in.
What happens when you plug a GFCI protected extension cord into an outlet that is GFCI protected?
In a word NO, that will not cause either GFCI to trip. The correct term is GFCI (Ground Fault Circuit Interrupter)
When there is a lot of rain the outside GFCI trips even though it is covered?
my gfci trips when my christmas lights r on and it rains is the gfci bad or is this normal of a perfectly working gfci
When would it be a better idea in a residence to install a GFCI breaker instead of an GFCI outlet?
GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.

What is the trip time for a GFCI?
The trip time for a GFCI is from 15 to 30 milliseconds.
How many amps does gfci trip at?
GFCI receptacle are designed to trip on 5 milliamps.
If the test switch is bad on a gfci will the breaker still work?
If the test switch is faulty then there is no convenient way to determine if the GFCI is functioning, and technically, if the test switch is faulty, then as it is a part of the GFCI, the GFCI is faulty and should be replaced.
Do all electrical outlets in a garage need to be GFCI?
Yes, but you can feed multiple outlets from one GFCI outlet. Make the first outlet fed in the cicuit a GFCI. Search for GFCI outlet with Google, etc. and I'm sure you will find an explanantion of how. Most GFCI's come with instructions also.
