That depends on the components in the circuit: resistive, reactive, nonlinear, etc.

What happens to a parallel circuit resistance if the voltage applied is doubled?
That has no effect on the resistance. The current doubles also.
What is kilo amperes?
The correct expression is 'kilovolt amperes' (kV.A), and it is a multiple the unit of measurement ('volt ampere') for the apparent power of a load in an a.c. circuit -i.e. the product of supply voltage and load current.
If the voltage is 12 volts and the resistance is 3 ohms what are the amps in this circuit?
Using Ohm's law, we can find the current (I) in a circuit where 3 ohms is the resistance (R) and 12 volts is the appllied voltage (V). [(E) means energy]I = V / R = 12 / 3 = 4 amps.Visit this link http://www.csgnetwork.com/ohmslaw2.html for making Ohm's Law calculations.
What is a ametre?
Are we talking electricity here? And a meter for testing current flow? An ammeter measures the amount of current (in amperes) in a closed, powered electrical circuit. The formula, e=i*r (Voltage = current * resistance) when solved for i is i=e/r So if you have 120 volts flowing through a circuit that has a total resistance of 8 ohms, the current would equal 120 / 8 or 15 amperes. - wjs1632 -
How is the voltage of the power supply for a series circuit calculated?
The circuit by itself doesn't determine the voltage of the power supply. If there's some additional requirement that goes along with the circuit, such as "The current through the circuit must be XYZ amperes.", or "The voltage across the third component from the north end of the circuit shall be ABC volts,", then that requirement would dictate the power supply voltage. But in order to calculate it, you'd need the knowledge of every component in the series circuit.
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 is the differnece between volts and amperes?
Voltage is power Amperage is current. you can have voltage but nothing runs without a closed circuit and then current flows.
How many amperes of current will flow in a circuit if the voltage difference is 9 V and the resistance in the circuit is 3 Ω?
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
What happen to current in a circuit if the voltage is not charge but the resistance is doubled?
The current in the circuit will be decreased by half. Ohm's law states V=IR so, I=V/R. If R is doubled, then I= V/2R.
What is the current when a voltage of 36 volts is applied to a circuit with a resistance of 6 ohms?
Six amperes. Use Ohm's law: the current is the voltage divided by the resistance
Does voltage play a role in an electromagnet?
Voltage is the "pressure" that pushes electrons thru a circuit, higher voltage means more current, or amperes. Amperes and the number of turns of wire in the magnet control the force of the magnet
What is the effect on current in a wire if both the voltage across it and its resistance are doubled?
it will cause a Short Circuit
If a circuit has a resistance of 4 ohm's how much voltage is needed to produce a 1.4 current in the circuit?
Voltage across a resistance = (resistance) x (current through the resistance) =4 x 1.4 = 5.6If the ' 1.4 ' is Amperes of current, then the required voltage is 5.6 volts.
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 is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
What happens to a parallel circuit resistance if the voltage applied is doubled?
That has no effect on the resistance. The current doubles also.
A circuit has total resistance of 5 ohms and a current of 0.3 amperes What voltage must the battery supply?
1.5 volts
