This sounds like highschool physics homework. The answer is simple ohms law and algebra. The short answer is Voltage = Current x Resistance. If you know two things you can find the third.
To be honest, this is a simple question and your book or Wikipedia can tell you. Just solve for the unknown.

What is the relationship between the voltage output at the interface and the voltage across the series and parallel circuit?
Ohm's law states that the current in a circuit is inversely proportional to the circuit resistance. There is a single path for current in a series circuit. The amount of current is determined by the total resistance of the circuit and the applied voltage.
What is the difference between resistance and resistor?
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors
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
In a parallel ac circuit is the current additive?
Yes In parallel circuit , current entering into the circuit will be divided intodifferent paths ( resistances) . Amount of current flow depends upon the magnitude of resistance applied in the circuit. Total current after passing through the circuit will be the sum of all current through each resistance.
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.
Calculate the resistance in a circuit in which a 9 volt batteriyproduces 3 ampheres?
V=IR so, R=V/I or resistance = Voltage / Amps Therefore, the resistance (R) = 9 volts / 3 Amps answer: 3 Ohms
A circuit has an applied voltage of 100 volts and a resistance of 1000 ohms What is the current flow in the circuit?
A circuit has an applied voltage of 100 volts and a resistance of 1000 ohms. The current flow in the circuit is 100v/1000ohms which would equal .1.
What does a current in a circuit depend on?
current depends on applied voltage and resistance.
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 Power that is applied to an entire circuit consisting of resistance capacitance and inductance is called?
The unit of power measured is watt, irrespective of resistance, capacitance or inductance of the circuit.
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
Why is there no flow of electric current?
There are two possible causes: 1. The circuit has no Voltage applied to it. 2. The resistance of the circuit is INFINITE.
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.
What is the mathematical relationship between heat dissipation and applied voltage?
Heat dissipation = (applied voltage)2 / total effective resistance of the circuit
What is the relationship between the voltage output at the interface and the voltage across the series and parallel circuit?
Ohm's law states that the current in a circuit is inversely proportional to the circuit resistance. There is a single path for current in a series circuit. The amount of current is determined by the total resistance of the circuit and the applied voltage.
How does resistance affects electric current?
Ohm's law states that the current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance of a circuit.
What is the difference between resistor and resistance?
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors
