Unless you do not have enough space in the service panel it is always a good idea to have each room on it's own circuit. If you want to put 2 rooms on a circuit just make sure those 2 rooms do not overload the circuit and wire it for a 20 amp circuit. Two bedrooms with 8 outlets each and 1 light each is about all you would want on the circuit. I would never put 3 rooms on the same circuit.
There are many types of electrical circuits and each one is wired differently. Without knowing the specific circuit that needs to be wired, this question can not be answered.
A 15a circuit can supply approximately 1650 watts, so 1650/65=25. I would stop at 20.
a schematic circuit is a diagram that show you how a particular circuit works
Circuit breakers are in place to prevent an over-current condition. When too much current is passed through a wire, it overheats and can result in fire. The circuit breaker is just doing its job when it turns off a circuit in that kind of condition. Too many appliances running simply means too much current on a circuit.
There are 1,000 miliamps in 1 amp. As the NEC limits you to loading a lighting circuit to no more than 80% you can have 16 amps or 16,000 miliamps on that circuit. That would mean you can have 2,000 lamps of 8 miliamps each.
The correct term is 'milliohm', not 'mill ohm'. As a milliohm is one-thousandth of an ohm, 500 milliohms is 0.5 ohm.
12 milliamp is 12 thousandths of an amp or 0.0012
Since "milli" means "thousandth", there are 150 milliohms in 0.15 ohms.
2 amps mili means 1,000
Volts and Amps are different units and can't be compared as you suggest.
0.8 amps is equivalent to 800 milliamps.

As an example, 0.001 amps is 1 milliamp.
4-20 milliamps refers to a standard analog signal that is used in many instrumentation circles. For example a tank level transmitter will send a 4 milliamp signal when the tank is empty and a 20 milliamp when the tank is full. 12 milliamp would indicate 1/2 full. Anything less than 4 milliamps is considered a broken wire or failed powersupply. This is the standard often used in the US. Germany often uses 0 to 20 millamp signals.
A metre is a unit of length. A milliamp is a unit of electrical current. Therefore, the two units are incompatible.
It depends on how many Milliamp you push the 1w led. Most 1w leds are not 1w of power but less, so that they dont burn out fast. So the answer would not be 1w but truely less than 1w.
