Transcribed Image Text:7.11.1 For the RL circuit shown in the image below, the switch has been closed for a
long time, and it opens at t= 0. If R1 = 6 S2 and R2 = 4 S2, determine the energy
stored in the inductor when t = 0. Please pay attention: the numbers may change
since they are randomized. Your answer must include 3 places after the decimal
point, and the proper Sl unit.

- A battery, resistor, capacitor and switch are connected in series to form an RC circuit as shown below. The switch is closed at time t=0 s. Which of the following statements regarding the circuit is correct? Switch S t M R C + 1 O The potential difference across the capacitor is always greater than the potential difference across the resistor O The potential difference across the resistor is always greater than the potential difference across the capacitor. O Once the capacitor is essentially fully charged, there is no appreciable current in the circuit. O The capacitor charges to its maximum value in one time constant and the current is zero at that time. O The potential difference across the resistor and the potential difference across the capacitor are always equal.arrow_forward4) Consider the circuit shown in the Figure, where C₁ = 6.00 µF, C₂ = 3.00 μF, and AV=20.0 V. Capacitor C₁ is first charged by the closing of switch S₁. Switch S₁ is then opened, and the charged capacitor is connected to the uncharged capacitor by the closing of S₂. Calculate the final charge on C₂.
