When does the electric current flow?
An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).
If you multiply the voltage in a circuit by the current what are you going to get for your answer?
Voltage x current = power (watts)
What is the relationship between voltage and current in an inductive circuit?
Current lags voltage in an inductive circuit. The angle by which it lags depends on the frequency of the AC, and on the relative size of the inductance compared to the resistance in the circuit.
In a series circuit what happens to the current if you increase the number of components in the circuit?
The current (amps) will remain constant, but the voltage will drop.
What effect does an increase in current have on voltage?
That depends on the circuit - but note that in almost all real circuits the current is the dependent variable - you control the voltage and the current sets itself.
If voltage changes in a ac circuit what happens to current?
Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.
Even without current flow there can be voltage in a circuit?
Voltage is potential energy and can exist in a open circuit.
What are three important characteristics of electric circuit?
Voltage, frequency, current, impedance, and what the circuit is supposed to do are all important.
Can you increase current in a circuit without change in resistance and voltage?
no it is not possibleAnswerYes, by changing the voltage OR the resistance.
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 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.
Does the current generates if there is no resistance in the circuit?
You can have current without resistance. You would just have zero voltage drop across that zero resistance.However, the question is very interesting, because if you really had zero resistance in the entire circuit, it would be impossible to have any voltage at all without generating an infinite current, so the answer in the theoretical case is no, you can have no current, nor voltage, if there is no resistance at any point in the circuit.
Can current flow in a circuit without potential difference?
A current cannot exist without voltage but voltage can exist without current.Simple example is battery. A battery has votlage even though it is not connected elsewhere.
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What is a relationship among voltage current 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 voltage error circuit and current error circuit?
A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.
