Does the current ina circuit increase with increase in temperature?
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.
When resistance decreases what happens to current?
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
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.
What would happen to the potential difference if the resistance stays constant and the current increases?
According to ohms law (V=IR)if voltage is increased the current also increases keeping the resistance same .In other words, to keep values on the both sides of equal sign current must increase with the voltage when the resistance is constant. For example: if R=1 and V=2 then I=2 and if voltage is increased to 4 then current also increases with voltage to 4.CONCLUSION:V IS DIRECTLY PROPORTIONAL TO I KEEPING THE R CONSTANT
How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?
If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
If resistance goes up does current go down?
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
How does current vary with the resistance in the circuit if the voltage is constant?
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.
What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
Does the current ina circuit increase with increase in temperature?

What happen to the current when the voltage increased if the resistance are constant?
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
When current remains constant and resistance increases the voltage in the circuit will?
The physical equation governing voltage is V = IR, where V is voltage, I is current, and R is resistance. If V remains constant while R is increased, I or current must decrease. Increasing the resistance in a circuit is simply introducing a material that further resists or impedes the electron flow (current), thus current decreases.
Does increasing the resistance increase the electric current?
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
Effect on voltage as current increases through constant resistance?
If the current is held constant, the voltage will decrease.
