E = I* R is Ohm's Law.
Where:
E = voltage
I = current
R = resistance
Using simple algebra yields: R = E / I
To find the net resistance of the circuit connected to the battery in the figure, you need to calculate the total resistance by adding up the individual resistances in the circuit.
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
The test equipment needs two test leads to find the resistance in a circuit.
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.
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 ()
The resistance of the circuit is measured in ohms.
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.
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.
The resistance of the circuit is measured in units of ohms.
Not sure what you mean. The equivalent (total) resistance in a parallel circuit is less than any individual resistance.
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.
