🔍 Key Concepts

• RC time constant (τ) and how it is calculated from resistance and capacitance • How many time constants are typically used to consider a capacitor "fully charged" using the charging curve in the illustration • Converting units like microfarads and megohms into base units (farads and ohms) before multiplying

💭 Think About

• First, compute the RC time constant τ using the given C1 and R1 values; what is τ in seconds? • Look at the lower graph: at how many time constants does the curve reach about 99% of full voltage, which many texts treat as "fully charged"? • Once you know how many τ correspond to "fully charged," multiply that by your τ in seconds and compare to the listed answer choices.

✅ Before You Answer

• Be sure you convert 1 microfarad and 3 megohms into farads and ohms correctly before multiplying. • From the graph, verify at which time in RC constants the charging curve is essentially at 100% of full voltage. • After you find the total time, double‑check that your value matches one of the listed answer choices before deciding.
