Q

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?

🔍 Key Concepts

• Inductance vs resistance vs capacitance in an AC (alternating current) circuit • Common electrical units named after scientists: ohm, siemens/mho, henry, farad • What physical behavior a coil (winding) creates in a circuit

💭 Think About

• 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? • Which of these units is associated with electrostatic charge storage and which with magnetic field energy? • Which unit normally goes with a resistor, and which unit normally goes with a capacitor?

✅ Before You Answer

• Match resistance to its standard unit and eliminate that choice. • Match capacitance to its standard unit and eliminate that choice. • Recall which unit is used specifically for inductance of coils in basic electrical theory.
