Resistance is decreases then the voltage drop across it is decreases because of ohms law (V=IR),due to this power can also be decreases because of P=VI. so finally we can say that resistance decreases ,power also decreases.

As the resistance in a series circuit is decreased the amount of current in the circuit increases or decreases?
Increases the total resistance
How does increasing the resistance affect the current?
Increasing resistance decreases current.
If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
How does loading effect affect flow of current?
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
What is the relationship between Power Ampere and resistance?
power=i square*resistance or power=v suare/resistance
When resistance increases what occur to power?
It decreases
What happens to the power of an electric circuit of the resistance is decreased?
if the resistance is decreased and the current stays the same, then the power decreases.
If voltage remains constant and resistance decreases current flow?
the current will increase because of a lower level of resistance , hence more current will flow- easily
As the resistance in a series circuit is decreased the amount of current in the circuit increases or decreases?
Increases the total resistance
How does the increasing the resistance affect the current?
Increasing resistance decreases current.
What is negative resistance region?
The region where resistance decreases with increase in temperature.
What happens to the resistance of a filament if it is replaced by a thicker wire?
The resistance decreases
How does increasing the resistance affect the current?
Increasing resistance decreases current.
Why does power decrease when resistance increases?
First, this statement stands as long as voltage is constant. If you held the current constant then power would increase as resistance increases.V=IR. For a fixed voltage if you increase the resistance (R) then the current (I) will decrease - following the formula.Power = VI so as the resistance increases the value of VI (power) decreases as V is constant and I gets smaller.Therefore the power is decreasing as the resistance increases (when voltage is held constant).Hope this helps.
If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
What happens to the resistance of a filament if it is replaced by a shorter wire?
the resistance decreases APEX
When wire is thicker its resistance is?
When a wire is made thicker it's resistance decreases.
