current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.

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.
Can there be a current with no voltage?
No, There can't Be current without voltage
If the current flowing through an electric heater increases from 6 to 12 amp while the voltage remains the same the heat produced by the heater will be what?
Since power is current times voltage, doubling current while keeping voltage the same will double the power. Ignoring slight non-linearity, if the power doubles, the heat will double.
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.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
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.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
Is flow of induced current necessary when induces emf is being produced?
There is no such thing as an 'induced current'. Voltages are induced, not currents. If a voltage is self-induced into a coil, then that voltage will oppose any change in current. If a voltage is mutually-induced into a separate coil, no current will flow unless that coil is connected to a load.
What is alternating current produced by?
Alternating current is produced by generators or power plants that use magnetic fields to induce voltage and generate electricity. This type of current changes direction periodically, typically in a sinusoidal waveform.
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.
What came first the voltage or the current?
For a current to flow between two points, those points must have a potential difference (voltage) across them.
Why you need to connect resistor in series for the practical voltage source?
A resistor is connected in series with a practical voltage source in order to determine the current produced by the source.
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 the currents produced by a 1.5v flashlight cell and a 12v car battery compare?
The current produced by a 1.5V flashlight cell would be lower than the current produced by a 12V car battery. This is because current is directly proportional to voltage in a circuit with constant resistance, following Ohm's Law (V = IR). Therefore, the higher voltage of the 12V car battery would result in a higher current compared to the 1.5V flashlight cell.
What is the maximum inductor voltage when the inductor current is decreasing?
depending on the stray capacitance it can be from a few ten volts to a few kilo volts.
Can voltage difference or resistance kill you first?
Neither, it is current that kills.
