WebSep 12, 2024 · 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 WebOhm’s law is a law stated by Georg Simon Ohm that relates the voltage across a conductor to the current passing through it and its electrical resistance. It states that the voltage across two points in an electric circuit is directly proportional to the current passing through it, and the constant of proportionality is the resistance.
