Why are kitchens and bathrooms required to be on separate 20-amp receptacle branch circuits?
The NEC doesn't provide justifications for its requirements, but the likely reason is simply the amount of amps often drawn in kitchens and bathrooms because of all the appliances specific to these locations. NEC 210.11 requires a minimum of two 20 amp circuits for counter top receptacles in the kitchen, called Small Appliance Branch Circuits.
It is my understand of the code that these small appliance circuits in the kitchen can also cover the dinning room, and similar areas in a dwelling, and while most electricians seem to frown on this, one of these circuits can be used for the refrigerator receptacle. One can also supply receptacles for any electrical stuff on gas-fired ranges. Dishwashers and waste disposals are not plugged in on counter tops so presumably need to be supplied by (a) circuit(s) other than these. On counter tops in the kitchen all receptacles must be GFCI protected.
The bathroom circuit is intended to either a) serve a GFCI receptacle at the sink and can also serve another such receptacle in another bathroom, but in this case cannot serve other loads in the bathroom, or b) can serve the receptacle and other permissible loads in the same bathroom but no loads outside of it.
Answer
In real life, our kitchen circuit also serves the dining room. Because we did not increase the capability of the circuit when we added the microwave, the dining room light dims out when we use the microwave. There would be similar issues with kitchen and bathrooms sharing one circuit.
It is funny how real life so often is "out-of-code". Following the current code, the lights in the dinning room would not dim because the two-small appliance circuit described above is only intended to serve receptacles in the kitchen and dinning room, and similar spaces in a dwelling, and so putting lights (any lights that are not lamps plugged into to wall receptacles) on them would not be permitted. In other words, your lights and your receptacles should not be on the same circuit, according to the NEC

Why are kitchens and bathrooms required to be on seperate 20-amp receptacle branch circuits?
Kitchens and bathrooms have specific electrical requirements to ensure safety. Separating them onto separate 20-amp circuits reduces the risk of overloading the circuit, as these areas have high electrical demands. It also helps prevent disruptions such as tripped breakers that could impact the usage of both spaces.
Where are receptacles required?
Receptacles are required in all habitable rooms, including bedrooms, living rooms, kitchens, and bathrooms. They are also required in hallways, stairways, and outdoor areas. Building codes dictate the specific locations and number of receptacles needed in a dwelling based on the square footage and layout of the space.
What would a GFCI protect you from?
Death possibly. If your body completes the electrical circuit, the ground fault interrupter will switch the power off and save you from electrocution. Required where electricity is being used around sinks (kitchens, bathrooms) and outdoors.
Explain the rules for GFCIs in bathroom wire size wiring?
In bathrooms, GFCI protection is required for all receptacles to prevent the risk of electric shock near water sources. The wire size for GFCI-protected circuits is typically required to be 12-gauge copper wire to handle the higher current demands in bathrooms. This ensures safety and compliance with electrical codes.
Where are GFI circuit breakers required for single family home?
Check with your local building department for specifics, but generally they are required in kitchens, baths, and outdoors
Do most kitchens have a 20amp outlet?
By today's NEC standards, all kitchens are required to have to have a minimum of two 20 amp circuits.

In what specific locations are arc-fault breakers not required to be installed?
Arc-fault breakers are not required to be installed in specific locations such as bathrooms, kitchens, garages, and unfinished basements.

Where are gfci outlets required?
GFCI receptacle's must protect any outlet that is within 6 feet of a water source, outside the home, in a garage, on a deck, in a sunroom, in a bathroom, unfinished basements, kitchens, & crawl spaces.
What are the main difference while applying kirchoffs laws to dc circuits and ac circuits using meter readings?
For DC circuits, an alebraic sum is required. For AC circuits, a phasor sum is required.

Do electric circuits have two switches?
They can, but not required.
Are all new bathrooms required to be ADA compliant?
All Public restrooms.
Are gfci receptacles required in kitchens?
No, you could use a GFCI circuit breaker instead.
Is a receptacle required in a hallway in a home when the hallway is 8 ft long?
no,only if its 10ft or more.
Is a receptacle required in a bedroom on a 3 ft wall space behind the door?
No, not behind a door.
