Does an open resistor measure 0 ohms?
No, an open resistor has a value of infinity. An open resistor typically will measure over 900 Megohms. A zero ohm resistor is exactly that, and will measure zero ohms. They are typically surface-mount devices.
How does a resistor in a circuit effect similar to open circuit?
Resistors resist amounts of the electricity flowing through the circuit.For example if the resister has these strips of colors on it in this order(red,green,blue) then the resister has 25,000,000 ohms. That means that the lamp(s)/ bulb(s) is(are) going to be very going to be very dim. Because, the more ohms the dimmer the light, the less ohms the brighter the light. But we should get back on task. A resistor effects a circuit because it makes the lamp(s)/ bulb(s) brighter of dimmer depending on the amount of ohms they have.
How many ohms can a resistor have?
An almost unlimited number. Several million or several tens of millions of ohms are possible. At some point there is so much resistance that the resistor is almost considered to be an "open" or "open circuit" of the like. Bleeder resistors for bleeding off extremely high voltages or for use in voltage dividers used in high voltage applications can have extreme resistance values.
What resistor to use to drop 9volt's dc to 6 volt's dc?
To drop a 12 volt source to 6 volts with a resistor, you have to drop 6 volts. The value of the resistor you need would be 6 divided by the current the device pulls in amps. For example, if the device pulls a half an amp the resistor has to be 6/0.5 or 12 ohms. As this device runs on 6 volts and draws 1/2 amp, it's wattage is 3 watts (volts x Amps). Common practice is to double this, or the resistor will probably get too hot and may open. I'd use a 10 watt to resistor to maintain a good margin for safety, and they're readily available. Use a 12 ohm, 10 watt resistor.
What are the common defects of a variable resistor?
Normally if a resistor fails they will either increase in value or open up at all (open circuit).

Is 5 mega ohms considered an open when testing for ground?
As long as it isn't going to General Motors, yes.
How to know if the resistor is open and shorted?
I assume that the person asking the question meant "open OR shorted" as these are opposite terms. Most resistors will open when they are damaged. It is very rare to find one that is shorted. To determine if the resistor is open or shorted simply use a multimeter set to measure ohms. Place the leads across the resistor and it should read the resistance value of the resistor. If it measures max range of the meter (some digitals will display "OL") then the resistor is open. If it measures 0 or very close then it is shorted, which as mentioned above, is unlikely.

No power at the blower motor resistor?
Since you're checking the resistor, I would assume you checked the fuse/relay for the blower motor. If not check that. If you have then there would be an open wire between the relay and the resistor.
Can you power the Pyle PLMPA35 Mini Amplifier 12V 300W with a 4 ohm resistor instead of a 4 ohm fuse?
It is unclear what you as asking about as fuses are rated in Amperes not Ohms. A fuse that measures 4 Ohms would be defective (not good but not fully blown open either).
What are the ohms in an open device?
The resistance [ohms] of an open electronic device is, by definition, infinite, just like a perfect insulator.
What are infinite ohms?
That is an open line.
No spark on v star 650?
Check the pickup coil for continuity. Should measure approximately 180-220 ohms. I bet it is open.
