Use thicker wire. Doubling the diameter gives one quarter the resistance.

Why isn't resistance constant?
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
What is the part of a circuit the closes or opens the circuit?
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit
Is a switch a resistor?
It could act as one when the circuit is closed, but when the circuit is open, I believe you would define the air as the thing resisting current. In basic circuit problems the switch usually doesn't have any resistance of its own (ie as negligible as the resistance in a wire, so it is ignored).
The dc input resistance of MOSFET is?
it depends on the type of the circuit you are analyzing..it could be a voltage divider, emitter follower, be specific on what type of circuit and maybe i can help you aobut this question.
Why do some circuits need resistors?
A circuit does need resistance but not necessarily a resistor. without any resistance a circuit will be considered a "short circuit" and you power source will most likely overheat. Resistance can be created in millions of different ways. This could be something such as an or any other light source but also a module such as a capacitor resistor or diode. To get to you're question more directly a circuit needs resistance to keep from shorting out. A specific module(such as an LED) would need a resistor to lower the voltage so to a point where the module can accept the power without burning out.
What could you do to a closed circuit consistenting of a battery a light bulb and a switch that increase the amount of current?
To increase the current you either need to reduce the resistance of the load or increase the voltage. Typically a higher wattage light bulb will decrease resistance or you could put multiple batteries in series.

An open circuit has an infinate resistance?
There is no such a thing as infinite resistance but it could be a very high resistance.

The value of resistance of an short circuit?
The value of resistance when there is a short circuit varies depending on the nature of the fault, but it could be fractionally above zero or higher.

What is the resistance if the current is 0?
If you measure zero current, then there are two possibilities,and there's no way you can tell which one is true withoutanother measurement.-- The voltage across the circuit may be zero,and the resistance could be anything.-- The resistance of the circuit may be infinite,and the voltage could be anything.
Why could the total resistance of the circuit vary when measuring resistance using a multimeter?
Residence of one component varies overtime and from component to component.

What can you do as an airline to minimize ozone layer depletion?
As airline, you can decrease the amount of carbon dioxide. It could decrease the ozone depletion.
