🔍 Key Concepts

• Capacitance is measured in farads, but capacitive reactance is not the same thing as capacitance • In AC circuits, resistance and reactance are both measured using the same unit • Think about what unit is used for opposition to current flow in a circuit

💭 Think About

• What is the unit of measure for basic resistance in a DC or AC circuit, and does reactance behave similarly in terms of opposition to current? • How does the unit for capacitance (like a storage tank for charge) differ from the unit for something that opposes current flow? • Which of the options represent: a unit of inductance, a unit of conductance, a unit of opposition to current, and a unit of capacitance?

✅ Before You Answer

• Be clear on the difference between capacitance (a property of a component) and capacitive reactance (its opposition to AC current) • Identify which option is the unit for opposition to current flow in a circuit • Eliminate the options that are clearly units for inductance, conductance, or capacitance, not opposition
