Is the open circuit voltage of a solar cell measured under non-illuminating condition?
Well, you should really measure the open-circuit voltage and the short circuit current both under dark and light conditions and then compare them to fully characterize a solar cell. Measuring the open-circuit voltage means measuring the voltage across the cell when no current is flowing (i.e., with a LARGE resistance as a load on the cell). Measuring the short-circuit current means measuring the current when the voltage across the circuit is essentially zero (i.e., with a VERY SMALL resistance as a load on the cell--thus, "short-circuit" current).
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.
What would the results of voltage drop test be if the circuit is open?
voltage drop is zero bcz in open ckt current will be zero
What is short circuit voltage?
Short circuit voltage is the voltage that has to be applied to the primaries of a transformer, so that the nominal current flows through the secondaries, when they are shorted. This value is important, if transformer secondaries shall be used in parallel. Ideally all transformers with parallel secondaries should have the same short circuit voltage. When their short circuit voltages are different, the transformer with the lower short circuit voltage will be loaded more than their relationship of power ratings would predict. The short circuit voltage is also important in the design of a transformer, because it predicts, how much the secondary voltage will drop at nominal output current. This knowledge helps the designer to find out, how many further windings the secondary needs for a certain voltage in relation to an ideal transformer. Short circuit voltage is also known as impedance voltage.
What is the symbol for a open circuit?
When a circuit is in off condition then it is called an open circuit..
Even without current flow there can be voltage in a circuit?
Voltage is potential energy and can exist in a open circuit.
What is open circuit characteristic?
The terminal voltage is equal to the supply voltage and there is zero current.
What is a circuit with no current running through it?
Such a circuit either has no voltage source, or some part of the circuit is open, e.g., an open switch.

How can you convert the voltage into milli amps?
Voltage is a property of electrical potential. Amperes (and miliamperes) are the units of electrical current. Even though these are related to each other in a circuit, they are not the same thing, and they cannot be "converted" into each other.Also, these properties are only related through a "load" the circuit provides (the resistance and inductance of the circuit), and make sense only when related to each other this way. If there is current, there will be voltage as well, but if there's only voltage, there will be no current unless there is some resistance as well (even a wire has resistance) - otherwise the circuit is "open" and no charge is flowing.In a simple circuit with a voltage source and resistor:milliamps = voltage*1000/resistance.If your circuit has diodes, capacitors, inductors, etc. it gets much more complicated.
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.
What quantity does the voltmeter measure when the switch is open?
When the switch is open, the voltmeter measures the potential difference or voltage across the two points connected by the switch, as no current flows through the circuit. This measured voltage is often referred to as the open-circuit voltage.
Can inserting a resistor in a circuit have an effect similar to an open circuit?
If the resistance is large enough, then there might not be enough voltage difference to allow much current. Since, Voltage = Current * Resistance, if resistance goes really large, and your voltage doesn't change, your current must decrease. An open circuit is where you do not have any current flowing, so whether no current verses very little current is the same is up to you.
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).
What would the results of voltage drop test be if the circuit is open?
voltage drop is zero bcz in open ckt current will be zero
What is typical open circuit voltage for an arc welding machine?
voltage available to the welding current via the machine
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
