If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
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 resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * 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.
As the DC voltage applied to a circuit decreases what will the current do?
In a passive circuit, the current will decrease. In an active industrial circuit, it will usually decrease. In a theoretic manner - it is an unknown.

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
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.
The amount of current in a circuit can what by increasing the amount of resistance present in the circuit?
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
If the resistance decreases in a circuit when the voltage remains constant the current will?
Current will increase
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.
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.
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 is the affect of a series circuit on current?
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .
Reducing the current you a circuit causes what?
Reducing the current to a circuit causes a higher resistance -- assuming constant Volts. Also, reducing the current to a circuit causes lower Volts -- assuming constant resistance.AnswerAltering the current has absolutely no effect on a circuit's resistance. Reducing the current will reduce line losses (I2R) and reduce the voltage drop along a conductor.
