Question
In charging RC circuits, the time constant is denoted by τ (tau). How is τ defined in terms of resistance (R) and capacitance (C)?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The time constant (τ) of an RC circuit is defined as the product of the resistance (R) and capacitance (C), i.e., τ = RC. It represents the characteristic time scale for the charging or discharging of the capacitor in the circuit, as mentioned on page 21.
Hint
Recall the fundamental formula for the time constant in RC circuits, which involves the product of R and C.
