Expert Solution & Answer
To determine
To check: Whether the given statement is true or false.
Answer to Problem 1TFQ
The given statement is
Explanation of Solution
A given circuit is a RC integrator circuit. Consider the circuit of an RC integrator shown below.
Here, input
In an RC circuit, the time taken for a capacitor to get fully charged or discharged is called transient time and it is expressed as 5 times the time constant of the circuit. The time constant of the circuit for a given value of resistance and capacitance is given by,
Hence, the transient time,
Thus, transient time and time constant are not the same.

First-order Low-pass RC Filter Analysis
The first-order low-pass RC filter shown in figure 1 below represents all voltages and currents in the time domain. It is of course
possible to solve for all circuit voltages using time domain differential equation techniques, but it is more efficient to convert the
circuit to its s-domain equivalent as shown in figure 2 and apply Laplace transform techniques.
