🔍 Key Concepts

• RC time constant (τ = R × C) and how changing R affects how fast the capacitor voltage rises or falls • Relationship between resistance (R) and current (I = V/R) during charging and discharging of a capacitor • How the graph in part B shows different slopes (fast vs slow) for charge and discharge when using different resistances

💭 Think About

• Look at the graph: which curve (charging or discharging) changes more quickly at the start, and what does that say about the resistance in that path? • If you want a small current, do you choose a high resistance or a low resistance? How will that affect how long the capacitor takes to reach a given percentage of full voltage? • Think about what “useful property” this circuit could provide: being able to charge the capacitor gently but dump its energy quickly. Which option describes that behavior?

✅ Before You Answer

• Make sure you link high R ↔ low current ↔ long time constant (slow change) and low R ↔ high current ↔ short time constant (fast change) • Confirm that the correct statement matches the shape of the curves in the illustration: one process is slow, the other is fast. • Verify that the option you choose has charging and discharging currents/times consistent with the basic formulas τ = R × C and I = V/R.
