Sure - an unconnected power supply of any kind - a battery is + at one end and - at the other.
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.
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
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.
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.
answer is actually voltage
No, There can't Be current without voltage
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.
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.
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.
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.
no it is not possibleAnswerYes, by changing the voltage OR the resistance.
YEs if Merlin is at the one end of the line and harry potter at the other, then it is possible.
Voltage is power Amperage is current. you can have voltage but nothing runs without a closed circuit and then current flows.
Voltage is potential energy and can exist in a open circuit.
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
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
In order to decrease voltage without decreasing amperes you have to also decrease resistance. Ohm's Law: Voltage = current times resistance
