The formula you are looking for is Ohm's Law. Voltage = Current x Resistance (v = I x R). To solve for Current the formula is I = V/R.

If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
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.
How will you convert a open current circuit to a open voltage circuit?
The first thing you need to know is the internal resistance of the current source, the voltage source will have the same internal resistance. Then compute the open circuit voltage of the current source, this will be the voltage of the voltage source. You are now done.
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 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 relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
How do you apply Ohm's law to a toaster?
The wires in a toaster are composed of a metal that heats up when you pass a current through the wires. The voltage, current and resistance for the toaster obey Ohm's Law (Voltage = Current x Resistance). When the wires heat up this heat causes the bread to toast. The toast is not part of the circuit and is not involved in Ohm's Law.
If you plug an electric toaster rated at 110-v into a 220-v outlet what will the outlet current in the toaster be?
It doesnt matter you will smoke it. The current in a resistive circuit is proportional to the voltage. If the voltage doubles and the resistance is the same (elements) the current will double and burn up both the elements and the toaster wiring. Look up "ohms law" for current voltage and resistance effects. Don't try it..
What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
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
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
How is the resistance of a resister calculated?
ohms law calculation for a series circuit - Total Resistance = Total Voltage divided by Total Current
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.
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
