- As the capacitor in an RC circuit charged, what is the current as a function of time?Explain physically.An RC circuit consisting of a resistor and capacitor is known to have a time constant of 0.800 s. How long would it take the capacitor to charge to 60.0% of its maximum value once the circuit is connected to a DC battery?Q1: A capacitor in a single - loop RC circuit is charged to 75% of its maximum charge in A seconds. What is the time constant for this circuit? A=4.575
- What multiple of the time constant t gives the time taken by an initially uncharged capacitor in an RC series circuit to be charged to 88.1% of its final charge? Number i Units4. You can easily find the time constant if you are given a graph of voltage across a discharging capacitor as a function of time. When t = Tc = RC, the voltage across the capacitor is AV (t = Tc) = AV, e¹≈ 0.37 AV Therefore the time constant is just how long it takes for AV (t) to reach 37% of its initial value. The graph shows the voltage across a discharging 0.2 μF capacitor as a function of time. Use the following steps to determine the resistance. a. What is 37% of the initial voltage? 21 b. How long does it take (after discharge starts) for the voltage to reach 37% of the initial voltage? This time is equal to the time constant. c.
