🔍 Key Concepts

• Relationship between capacitance in series and equivalent capacitance • Formula for capacitive reactance in AC circuits: ( X_C = \frac{1}{2\pi f C} ) • Using Ohm’s Law for AC magnitude: ( I = \frac{V}{X_C} )

💭 Think About

• Look at figure A: are C1 and C2 connected in series or parallel with respect to the AC source? How does that affect the equivalent capacitance? • Once you have the equivalent capacitance, how do you calculate the capacitive reactance at 60 Hz, and then the circuit current from the 240‑volt supply? • Compare the magnitude of the reactance you compute to a normal resistor: would a larger or smaller reactance give a larger current, and which answer choices match that size of current?

✅ Before You Answer

• Be sure you convert microfarads (µF) to farads before using the reactance formula. • Verify your equivalent capacitance for two capacitors in series: ( C_{eq} = \frac{C_1 C_2}{C_1 + C_2} ). • After finding ( X_C ), check that your current from ( I = \frac{V}{X_C} ) is reasonable for a 240‑V circuit and matches one of the choices.
