Why current source is replaced by open circuit across the terminals?

For an ideal current source, this means replace the current source with an open circuit. Resistance can then be calculated across the terminals.

No, the current flow is stopped by an opened circuit.

What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
How is a series circuit different to a parell circuit?
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
What happens in a circuit to voltage when current flows?
A: There is a relationship one needs the other both can coexists but not each alone.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
What is the current running through a 90 volt circuit?
It depends on the resistance of everything connected between the terminals of the power supply. If the resistance is infinite or very high, there is little or no current. As the resistance becomes less, the current becomes greater. In general, the current through a circuit with 90 volts applied to it is [ 90 / R ], where 'R' is the resistance of everything across the 90-volt power supply.
What is the current source replaced by open circuit across the terminals?
because an ideal current source is assumed to produce a constant current for any voltage and is assumed to have an impedence of infinity (open circuit).
How does voltage produce current?
Voltage across two terminals mean there exists a potential difference, and when the circuit gets closed, due to this potential difference the current flow.
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
What is maintained across the terminals of a battery?
Current
How is a series circuit different to a parell circuit?
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
What is use of terminals in the circuit?
Terminal represents or are ends in a Electrical Circuit that connects components in Circuit to the Power Source. Terminals are either Positive or Negative marked at the ends denoting the acceptible floe of electrons across the Circuit.
Do You measure current across a circuit?
A current flows through, not across, a circuit. And, yes, you can measure it using an ammeter.
Short circuit?
A somewhat imprecise term used to describe the condition of very low resistance across the terminals of a power source, resulting in very high current.
What happens in a circuit to voltage when current flows?
A: There is a relationship one needs the other both can coexists but not each alone.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
What is the Thevenin theorem?
The current flowing through the load terminals Rl connected across any two terminals A & B of a linear, bilateral, active network is given by Voc/Rth + RL where VOC is the open circuit voltage across the terminals A & B & RL is the internal resistance of the network as viewed back into the open circuited network from AB deactivating all the independent sources.
