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.
In a parallel circuit the voltage across each component is the same.

Voltage
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.
Yes. The voltage across every branch of a parallel circuit is the same. (It may not be the supply voltage, if there's another component between the power supply and either or both ends of the parallel circuit.)
Yes, if it is a series circuit. In an ideal parallel circuit, there is equal voltage in each leg. In a real circuit, results may vary if there is voltage loss in the wiring.
In a parallel circuit the voltage across each component is the same.

Voltage
A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same
A: the source voltage
When you plot a graph of voltage against current, you can end up with a straight line or a curved line.If you have a straight line, then it shows that the change in current is directly proportional to the change in voltage and, so, the circuit is obeying Ohm's Law. If the graph is a curve, then the change in current is not proportional to the change in voltage and, so, the circuit is not obeying Ohm's Law.In the case of a straight-line graph, the gradient of the graph indicates the resistance of the circuit. The greater the gradient, the higher the circuit resistance.In the case of a curved-line graph, the gradient (i.e. the tangent) at each point along that curve will indicate the (changing) resistance at each of those points.
A parallel circuit has the same voltage but different current in each leg and series circuit has the same current but different voltage on each components unless the same value.
Yes. In a 240 volt circuit, the total applied voltage is 240 volts but each leg is carrying only 120 volts.
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
i.e normally we have various sensors to measure the voltage but my doubt is, how the voltage circuit measures the voltage i.e i need the detail for each and every unit.... If anybody know means plz tell to me.....
