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
It reduced to half
It is halved. coz voltage=current * resistance
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 voltage remains constant and resistance is increased, the amperage will decrease per Ohm's Law.
If resistance is halved while voltage remains constant, the current will double.
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.
nothing
It is halved. coz voltage=current * resistance
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.
Current will increase
The resistance is decreasing
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 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.
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
Current increases if the voltage remains constant.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
If voltage remains constant and resistance is increased, the amperage will decrease per Ohm's Law.
If resistance is halved while voltage remains constant, the current will double.
