What else can I help you with?
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.
What is knee voltage and breakdown voltage?
Knee voltage (cut in voltage) :-The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage Breakdown voltage :-It is the minimum reverse voltage at which the P-N Junction can conduct without damage to the current
Do appliances run on current or voltage?
This is a 'chicken and egg' situation. The motors in washing machines, etc., are driven by current but, without voltage, current cannot flow. You can't really separate the two.
How does the voltage applied to a circuit affect the current flowing through the wire?
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
As the voltage applied to a circuit increases the current and the also increase?
answer is actually voltage
Can there be a current with no voltage?
No, There can't Be current without voltage
Is the current produced by voltage or is it viceversa?
Voltage is responsible for the production of current. voltage is the unit of electromotive force which gives the electrons a motion in a definite direction which we call current. voltage can exist without current(i.e. in open ckt.) but current can not without voltage.
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.
Can voltage flow without use of wire?
We talk about current flowing, not voltage. Current can flow without wire as is witnessed in a lightening storm. Voltage can be transferred via induction through the air as well.
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.
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.
Can you have current without voltage in a circuit?
YEs if Merlin is at the one end of the line and harry potter at the other, then it is possible.
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.
Even without current flow there can be voltage in a circuit?
Voltage is potential energy and can exist in a open circuit.
What are ideal current and voltage sources?
Sources without internal resistances.ideal voltage source has 0 ohms in series with it, no internal voltage drop all voltage delivered to loadideal current source has infinite ohms in parallel with it, no internal current loss all current delivered to load
What is knee voltage and breakdown voltage?
Knee voltage (cut in voltage) :-The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage Breakdown voltage :-It is the minimum reverse voltage at which the P-N Junction can conduct without damage to the current
How do you decrease voltage in dc without decreasing amperage?
In order to decrease voltage without decreasing amperes you have to also decrease resistance. Ohm's Law: Voltage = current times resistance
