WebResistance is the measure of electrical “friction” as charges move through a conductor . It is measured in the unit of ohm, that unit symbolized by the capital Greek letter omega (Ω). Parts and Materials Multimeter, digital or analog Assorted resistors Rectifying diode Cadmium Sulphide photocell Breadboard Jumper wires Paper Pencil Glass of water WebWe do not want the voltmeter to load the circuit. Consequently an ideal voltmeter will have infinite resistance. An ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit. We will find the shunt as part of the ammeter circuit.
