What was the total voltage across both voltage sources connected together for the first circuit?
Sadly, I was not in the lab at the time, and did not observe the experiment. (I guess that makes two of us, eh ?)
What is The Voltage Of each wire in Straight 220V Circuit?
Voltage is not an absolute figure. Voltage Difference is the exact term. So, the voltage difference between the two wires in the 220 V circuit will be 220V.
What does volt measure?
Voltage measures the electrical potential between two parts of an electrical circuit. Also called electromotive force. Voltage provides the 'pressure' to drive electrons round a circuit.
What is the difference between independent and dependent source?
Independent SourcesIndependent sources produce current/voltage at a particular rate that is dependent only on time. These sources may output a constant current/voltage, or they may output current/voltage that varies with time.Dependent SourcesDependent sources are current or voltage sources whose output value is based on time or another value from the circuit. A dependent source may be based on the voltage over a resistor for example, or even the current flowing through a given wire. The following sources are possible:Current-controlled current sourceCurrent-controlled voltage sourceVoltage-controlled current sourceVoltage-controlled voltage sourceDependent sources are useful for modelling transistors or vacuum tubes.
What is the use of superposition theorem?
superposition can find the voltage and current effect of each source to a particular branch of the circuit and we can calculate the total effect of the sources to know the effect of the total sources to that branch
What are 2 sources for a circuit?
voltage source and current source
What is a Thevenin's equivalent circuit consists of?
A Thevenin's equivalent circuit is a single voltage source in series with a single resistor. It is electrically the same as any combination of voltage sources, current sources, and resistors that, as a black box, has two terminals. The technique is useful in simplifying circuits, when analyzing them.
What provides the voltage difference in an electric circuit?
Voltage sources provide the voltage difference across an electrical circuit, these may be batteries, generators, alternators, solar cells, etc.

Why kirchhoff's voltage law is applicable for open circuit?
Kirchoff's Voltage Law does not work, per se, for open circuits. You need a closed circuit for it to make any kind of sense.The signed sum of the voltage drops going around a series circuit is equal to zero.That means you have a closed circuit.However, it can be argued, correctly, that an open circuit is simply one that has two nodes with infinite resistance between them. Assuming that all of the other nodes have something less than infinite resistance between them, then Kirchoff's law does work, of sorts, in that the voltage drop across all nodes that are not voltage sources will be zero, because there is no current, and the voltage drop across the two nodes with infinite resistance will be equal to the sum of the voltage rises across the voltage sources. Current sources in such a circuit will not work, because, with zero current, they would attempt to generate infinite voltage.AnswerKirchhoff's Voltage Law does indeed apply to an open circuit, because the voltage drop across the open part of the circuit is numerically equal to the supply voltage and, hence, the algebraic sum of the voltage drops around that particular loop is zero.Kirchoff's Voltage Law does not work, per se, for open circuits.

What happen to the current values when one of the voltage sources is disconnected from the circuit?
Without the actual circuit diagram (schematic), this question cannot be answered.
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.
Describe the difference between a sourcing input and a sinking input?
An NPN or sinking output accepts voltage and sinks it to ground to complete the circuit. A PNP or sourcing output sources voltage and the external circuit sinks it to ground to complete the circuit. A sourcing circuit would be drawn as voltage->switch->load->ground. A sinking circuit would be drawn as Voltage->load->switch->ground. In these cases, the switch could be a transistor.
The difference between short to a voltage circuit and short to a ground circuit?
A short circuit is an abnormal connection between two nodes intended to be at different voltages. A voltage circuit is caused intentionally for the purpose of voltage sensing. A ground circuit occurs between a phase and the ground.
What is The Voltage Of each wire in Straight 220V Circuit?
Voltage is not an absolute figure. Voltage Difference is the exact term. So, the voltage difference between the two wires in the 220 V circuit will be 220V.
What are two examples of voltage sources?
batteries and generators
What are the two common sources of electrons in a electric circuit?
The electrons are always there, for example in the metal. You don't need a special "source" for electrons in a circuit. What you DO need is a voltage source, i.e., something that pushes the electrons around.
