Question 1 of 27070

The time in seconds for a capacitor to attain 63.2 % of the applied voltage across its terminals is:

🔍 Key Concepts

• Charging of a capacitor in an RC circuit • The meaning of 63.2% of final (applied) voltage in transient analysis • Definition and units of a circuit time-related parameter

💭 Think About

• When a DC voltage is suddenly applied to a resistor–capacitor (RC) circuit, how does the capacitor voltage change with time? Is it linear or exponential? • What special time value is used by engineers to describe how fast a capacitor charges or discharges to a certain fixed percentage of its final value? • Look at each choice: which one is a standard term used to describe the speed of charging in RC circuits, and which options clearly do NOT relate to capacitor charging time?

✅ Before You Answer

• Recall the exponential charging formula for a capacitor and identify what time corresponds to about 63% of the final voltage. • Check which option is defined as having units of time (seconds), not frequency, voltage, or resistance. • Eliminate any term that is unrelated to RC transient response or that refers to a physical component property rather than a time measure.
