That depends on the components in the circuit: resistive, reactive, nonlinear, etc.
If resistance is doubled in a circuit with constant voltage, Ohm's Law (V=IR) states that current (I) would be halved since the voltage is constant. This is because the relationship between resistance and current is inversely proportional.
To calculate amperes, you can use Ohm's Law: amperes = voltage ÷ resistance. Current is the flow of electric charge, measured in amperes, that passes through a conductor in a unit of time. You can measure current using an ammeter in a circuit.
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.
If the number of receivers (branches) in a circuit is doubled, the overall current of the circuit would also double, assuming that the voltage remains constant. This is because current is divided equally among the branches in a series circuit, so increasing the number of branches would result in each branch carrying less current if the overall current remained the same.
Use the equation, V= IR from Ohm's Law V is the voltage, I is the current, and R is the resistance in ohms So then, solve the equation for I (the current) and you get I=V/R. Then just plug in the values... I= 12/3, which equals 4 A. (For current, it is measured in amperes, or just "A" as the unit.)
It is halved. coz voltage=current * resistance

Voltage is power Amperage is current. you can have voltage but nothing runs without a closed circuit and then current flows.
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.
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
To calculate amperes, you can use Ohm's Law: amperes = voltage ÷ resistance. Current is the flow of electric charge, measured in amperes, that passes through a conductor in a unit of time. You can measure current using an ammeter in a circuit.
Six amperes. Use Ohm's law: the current is the voltage divided by the resistance
it will cause a Short Circuit
In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.
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.
Electrical current is measured in amperes.
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.
