Depends on what the outlets are controlling, size of the wire, and size of the breaker.

ViviIn Canada the CEC states there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.
In the United States, in commercial and industrial installations, you are limited to 10 receptacle outlets on a 15 amp circuit and 13 receptacle outlets on a 20 amp circuit. This is computed by rating each outlet at 180 watts and dividing that into the maximum rated wattage of the circuit. On lighting circuits you are limited to 80% of the rating of the circuit without any other limitation on how many lights can be connected.
In dwellings in the United States there is no limitation on how many outlets (which is the box, not the device) that can be placed on an individual circuit. This is because it is presumed that, assuming the system is professionally installed, it is highly unlikely to overload an individual receptacle circuit in a home. It does happen, but the breaker protects the circuit.
You run into this problem most often in older homes where having a toaster, coffee maker, microwave, refrigerator, ceiling light, etc etc was never imagined. Newer homes are wired to reduce the likelihood of this problem.

What might cause low voltage at one outlet on a multioutlet circuit?
its an overload on the circuit breaker the 3 outlets are on.. many times groups of outlets are on different circuit breakers.. even though they are in the same room... especially if some are on a gfi outlet
How many outlets are there?
Up to 12 on a 20 amp circuit. Up to 9 on a 15 amp circuit. But use common sense. If the circuit will be heavily loaded, as in a home office, then do not install that many.
How many lights off one switch?

How many wall outlets can you have in a circuit using a A breaker?
Assuming this is not an office of a place where lots of the outlets will be used to power items that draw lots of current on a 15 amp circuit wired with 14/2 wire I would limit it to no more than 10 outlets and lights combined. On a 20 amp circuit wired with 12/2 wire I would limit it to a 14 outlets and lights combined. There is no limit in the code. You just use common sense based on what is going to be used on this circuit.
How many eletrcal outlets can you have in a garage?
There is no limit as to the amount of circuits you can have in a garage. If you mean how many devices on a 15 amp single circuit breaker then the answer is 12. Be sure to total in light fixture outlets and switch boxes.
