Answer:
factors=
area of cross section, length of cross section , and type of material
defination = which resist the flow of current in the circuit .
resistance = from ohms expt. in a circuit the the voltage across the circuit is directly propotional to current in that circuit .

Answer:
Electric resistivity of a material is known as Rho. It doesn't have any unit cause it is a ratio
Explanation:
Make a circuit of a battery switch and a bulb with copper wire then silver and any other available material join it with a reohstat and notice the resistance different material will have different resistance
