the power will be reduced to the haflf because P=V2/R so when the resistance doubles the power reduced to the half of itsoriginal value

If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What happens to the current flowing in a circuit if its resistance is doubled?
Using Ohms Law: V = I x R, where V (Voltage), I (Current), and R (Resistance). re-arranging: V/R = I Therefore if you double both the Voltage and the Resistance, the current remains unchanged.Current = Voltage / Resistance. If both resistance and voltage double the current remains the same.
Doubling the resistance in a circuit will increase or decrease amperage?
If voltage remains constant and resistance is increased, the amperage will decrease per Ohm's Law.
Will doubling the resistance in a circuit halve the current if voltage is held constant?
If resistance is halved while voltage remains constant, the current will double.
In a series circuit each device that is added to circuit decreases the?
Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.
What happens to a parallel circuit resistance if the voltage applied is doubled?
In a parallel circuit, the total resistance remains the same when the voltage applied is doubled. Each branch in the parallel circuit will experience the same increase in voltage, but their individual resistances will remain constant.
What happens to current flow if circuit resistance increases and voltage remains the same?
nothing
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What happens to the resistance when the frequency is doubled?
When the frequency is doubled, the resistance of a circuit remains unchanged. Resistance in a circuit is independent of frequency and is determined by the material and physical dimensions of the resistor.
How long does current remain in a 220 volt circuit?
The current in a 220 volt circuit depends on the resistance of the load connected to it. Ohm's Law (I = V/R) states that current (I) is equal to voltage (V) divided by resistance (R). So, the current will vary based on the resistance of the circuit.
If the resistance decreases in a circuit when the voltage remains constant the current will?
Current will increase
When the voltage in a series circuit is doubled while the resistance remains the same the power increases by?
If the voltage doubles while the resistance remains the same, the power increases by a factor of four.Power = voltage times currentCurrent = voltage divided by resistanceSo, power = voltage squared divided by resistanceThis has nothing to do with being in a series circuit. It is simply Ohm's Law and Joule's Laws.
What happens to the current flowing in a circuit if its resistance is doubled?
Using Ohms Law: V = I x R, where V (Voltage), I (Current), and R (Resistance). re-arranging: V/R = I Therefore if you double both the Voltage and the Resistance, the current remains unchanged.Current = Voltage / Resistance. If both resistance and voltage double the current remains the same.
If the voltage applied to a circuit remains constant and the resistance in the circuit is increased the current will?
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
What happens to the current in a circuit if the resistance in increased.?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
