WebThe circuit is therefore completed through a second resistor, termed the main shunt ; as with a potentiometric recording system the connexions are made to the ends of this resistor, thus enabling the corresponding voltage drop to be indicated. WebSep 12, 2024 · (a) The resistance can be found using Ohm’s law. Ohm’s law states that V = I R, so the resistance can be found using R = V / I. (b) First, the resistance is temperature dependent so the new resistance after the resistor has been heated can be found using R = R 0 ( 1 + α Δ T). The current can be found using Ohm’s law in the form I = V / R. Solution
