Document Summary

3 ohm "s law : resistance s resistors. V we find that the current in a wire is proportional p the potential. " this is called mm - s low. The ratio of voltage to current for a given material (cid:8869) r - Vii e v -- ir th is called resistance r : in many conductors, (cid:8869) relationship = mm "s law the resistance is independent of the voltage. " materials that do not follow rhm "s law are nonohmic resistance : mm er ) 1mm - " unit of flows from high potential p low potential current (cid:8869) electrons now in the direction opposite to current. Charge does not build up in a. Light bulbs are resistors since they offer resistance to current turning through them resistors are tailored so. Inside all out electronic devices in how by controlling the amount of current the circuit operates.
