If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.

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.


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.


Does the amperage double when you double both the current and the voltage in a circuit?

No, the amperage does not necessarily double when both the current and voltage are doubled. Amperage (current) is determined by Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). If both voltage and current are doubled while resistance remains constant, the new current would actually be four times the original current, not just double.


In a circuit is current proportional to resistance?

Ohms law is: I = V / R (current = voltage / resistance)... where if the voltage or resistance changes then the current will change. ... the current and resistance is a inversely proportional linearly relationship ...this means that if the resistance doubles then the current halfs, if the resistance halfs then the current doubles, etc...hope this helps


What is the effect on the current in a wire if both the voltage across it and it's resistance are doubled?

By Ohm's Law, current is voltage divided by resistance, so if you double both the voltage and the resistance, the current would remain the same.

What are the two reasons for the current to double in a circuit?

What would current amperes do if the voltage were doubled in a circuit?

If the voltage in a circuit were doubled, the current would also double according to Ohm's Law (I = V/R), assuming the resistance in the circuit remains constant. This is because current is directly proportional to voltage when resistance is held constant.


What happen to current in a circuit if the voltage in not charged but the resistant is double?

In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.


What would happen to the current in a simple circuit if a bulb with a higher resistance were used?

If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.


How does the voltage applied to a circuit affect the current flowing through the wire?

Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.


What happens to the current when the voltage is doubled and the resistance is constant?

If the voltage is doubled and the resistance is constant, Ohm's Law states that the current will also double. This is because the relationship between voltage, current, and resistance is linear, and increasing the voltage will directly increase the current flow.

The current flowing through an element in a circuit is directly proportional to the applied voltage?

Ohm's law states it is. Double the voltage with the same resistance will double the current. E = IxR. 120 = 10 x 12. 240 = 20 x 12.
