Introduction- The purpose of the lab is to verify the important linear relationship between potential difference and current, and to gain knowledge regarding division of voltage and current by resistances connected in series and parallel. We will be testing Ohm’s Law in this experiment, and the parts are the equation are, the V represents the potential drop across a conductor, measured in Volts (V); and R represents the resistance of the conductor, measured in Ohms (Ω) and lastly the I represents the current in the conductor that is measure in amperes, more commonly known as Amps (A). The equation can then be rearranged in order to find resistance. Useful Equations- V=RI (y=mx)-slop e being resistance rea rranged R=V/I (1/ Req)= (1/R1) + (1/R2) + … (parallel) Req= R1+R2+ … (series) % Error= {(exp – actual)/ actual} x 100 Data- Ohms Law Experimental Resistors Resistance (experimental)= 101.2 Ω from graph
