Alternating current circuits may develop resistance, inductance and capacitance. What would be the unit of measure used in measuring the inductance of a wound coil?
β’ Inductance vs resistance vs capacitance in an AC (alternating current) circuit β’ Common electrical units named after scientists: ohm, siemens/mho, henry, farad β’ What physical behavior a coil (winding) creates in a circuit
β’ Ask yourself: when current changes in a coil and it resists that change by storing energy in a magnetic field, what property is that, and what is its unit? β’ Which of these units is associated with electrostatic charge storage and which with magnetic field energy? β’ Which unit normally goes with a resistor, and which unit normally goes with a capacitor?
β’ Match resistance to its standard unit and eliminate that choice. β’ Match capacitance to its standard unit and eliminate that choice. β’ Recall which unit is used specifically for inductance of coils in basic electrical theory.
