What determines the actual magnitude and direction of current through voltage source?
The voltage itself will determine the direction of current (assuming there isn't another source pushing current through the source backwards); the amount of current will be determined by the thevenin equivalent resistance of the circuit connected to that source (the resistance "seen" by the source, which can be lumped into a single circuit element).
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 is infinite resistance in a circuit?
It isn't. If you're using superposition, you open circuit current sources and short voltage sources; this is because the current source declares the current that will be flowing through that branch. Both current and voltage sources have a finite internal resistance.
You have a circuit that has Voltage source of 9V and Resistance of 5k what is the Current in this circuit?
Ohm's Law Voltage = Current x Resistance V = I x R I = 9/5000
Does a voltage source have resistance?
Voltage source: is any source that voltage and amperage come from. Resistor: is any part of a circuit that consumes that energy!

What is difference between ideal current source and practical current source?
Internal resistance. The ideal current source has no internal resistance in parallel with it (if it was set to supply no current it would act as an open circuit), and all the current it supplied would have to flow through its load (even if the load was an open circuit, in which case the voltage across the current source would be infinite). A real current source has the practical limitation that it must have an internal resistance in parallel with it, therefor some of the current it supplied is bypassed through that internal resistance and never reaches the load (if the load was an open circuit, then all the current supplied is bypassed and the resulting voltage drop across the internal resistance limits the voltage across the current source).
In a AC parallel circuit which is constant voltage or resistance?
Voltage will be constant. Resistance is dependent on the components in the circuit. Source: Electronics Technician for the US Govt
What does a complete electric circuit have?
a power source, path, and load or resistance.

Would it be true to say that current causes voltage?
Volts = Current x Resistance. The voltage is where the potential resides for the amount of current flowing through a resistance. Think about the voltage as a potential source of electrons that then flow through a circuit depending on the Load, or resistance in this example.
Why do you replace voltage sources with short circuits and current sources with open circuits in thevenin's theorem?
The equivalent of an inactive Thevenin voltage source is a source with zero voltage between its terminals regardless of the current through it, best represented by a zero resistance, i.e. a short-circuit. The equivalent of an inactive Norton current source is a source through which no current can flow regardless of the voltage across it, best represented by an infinite resistance, i.e. an open circuit.
How electricityflows in a circuit?
Circuit has three components which electricity passes through. First is the power source, the supplier of electricity in a circuit. Second is the conductor that includes the wiring, switches, and any component that control the flow of electricity. Lastly is the load, or the devices that consumed the electricity. In conclusion the electricity flows from source to the conductor then to the loads.
What is an electric circuit with little or no resistance?
A: As current approaches infinity on a device it is known as a current source.
