In other words, with the perfect setup, you could put a digital panel meter that reads the voltage in the circuit, and read the resistance directly. Zeroing it out would require more effort to get ...

In other words, the voltages around the circuit add up to the voltage of the supply. The total resistance of a number of resistors in series is equal to the sum of all the individual resistances.

Resistance ® close resistance (R)How difficult it is for current to flow. increases when components, for example a lamp, are added to a circuit in series. Potential difference close potential ...
