OHMS LAW APPARATUS: Series, Parallel

OHMS LAW APPARATUS

•  Ohms Law Apparatuses to show interrelationship of current, voltage and resistance in electrical circuitry.

(Wikipedia excerpt: ... "...Ohm's law states that the electric current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance,[1] one arrives at the three mathematical equations used to describe this relationship:[2].  V = I R or I = V R or R = V I {\displaystyle V=IR\quad {\text{or}}\quad I={\frac {V}{R}}\quad {\text{or}}\quad R={\frac {V}{I}}} where I is the current through the conductor, V is the voltage measured across the conductor and R is the resistance of the conductor.

More specifically, Ohm's law states that the R in this relation is constant, independent of the current.[3] If the resistance is not constant, the previous equation cannot be called Ohm's law, but it can still be used as a definition of static/DC resistance.[4] Ohm's law is an empirical relation which accurately describes the conductivity of the vast majority of electrically conductive materials over many orders of magnitude of current. However some materials do not obey Ohm's law; these are called non-ohmic....")
