1.Resistance is dependent on the material.Like wood is insulator(ALMOST infinite resistance).
2.Resistance of a wire having more cross sectional area is less and less cross sectional area is more(i.e. it is inversely propotional to the cross sectional area.)
3.It is more for more length and less for less length.
4. Resistance varies with temprature.For metals like platinum it increses with temprature.
number and voltage of the cells in the circuit resistance of each bulb
They are not exactly the same. A series circuit is one complete circuit with not other pathways. A parallel circuit is a complete circuit with multiple pathways . The resistance of a parallel circuit is completely different from the resistance of a series circuit. Therefore, this affects the voltage and the current produced,
Continuity is checking for a completed circuit including a short circuit. Checking resistance would be checking in ohms resistance of a circuit, motor windings or an open circuit.
If you don't change the voltage between the ends of the circuit,then higher resistance in the circuit means lower current (amps).
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.

resistance is measured in 'ohms'. A thermistor basically tells u how temperature affects resistance in a circuit, generally the higher the temperature (degrees) the less resistance
Ohm's law states that the current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance of a circuit.
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
No it does not. A volt meter only reads the current that is passing through it.AnswerAll instruments draw some (albeit tiny) current from the circuit under test in order to operate. So, if this is what you mean by 'taking power from circuit', then the answer is yes, it does.Instruments also change the normal resistance of the circuit being tested -for example, ammeters increase the resistance of the circuit into which they are connected, while voltmeters decrease the circuit resistance across which they are connected. So adding a voltmeter (or an ammeter) to a circuit affects the operation of that circuit to some degree. To minimise this interference, it is important that an ammeter's internal resistance is very much lower than the circuit's resistance, and a voltmeter's resistance is very much higher than the circuit's resistance.
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
Not sure what you mean. The equivalent (total) resistance in a parallel circuit is less than any individual resistance.
On Circuit Resistance = Close to the total load Resistance. Off Circuit Resistance = Near Infinitive High Resistance.
