That entirely depends on whether the resistances are in series or in parallel with each other. Ohm's law states that I=V/R. i.e. current = voltage/resistance. If you know the current and voltage you can find the resistance. You can use algebra to rearrange the formula for R and get that R= V/I. Resistance = voltage/current.

Using ohm's law what is the formula to find the resistance in a circuit?

Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)


How many test leads are needed to find resistance?

The test equipment needs two test leads to find the resistance in a circuit.


How do you find the resistance of a series circuit with n identical resistors?

The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.


What would happen to circuit if there was no resistance?

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 ()


Is the increase in voltage causes a greater electric resistance in a circuit?

No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.


How is the total resistance in a series circuit is determined?

The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.


Is the sum of the resistance in a parallel circuit always excessds the total resistance in a circuit?

Not sure what you mean. The equivalent (total) resistance in a parallel circuit is less than any individual resistance.


Why isn't resistance constant?

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.


What is the difference between on and off state resistance?

On Circuit Resistance = Close to the total load Resistance. Off Circuit Resistance = Near Infinitive High Resistance.


What is the relationship among voltage circuit and resistance in a circuit?

Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)


What is the resistance in this circuit?

You would have to specify the circuit.


What is the difference between continuity and resistance check?

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.
