Consider the RC circuit shown in the figure below. The resistance of the circuit is R = 5.5k? and the capacitance of the initially uncharged capacitor is C = 8.9?F. If the emf of the battery the circuit is connected to ? = 17V and the switch is closed at t=0, determine the charge of the capacitor in units of ?C at the instant the current running in the circuit is at 22% of its initial value? Express your answer using two decimal places. Answer:

Close
Step 1
First, we need to find the initial current in the circuit when the switch is closed. Since the capacitor is initially uncharged, it acts like a short circuit, and the initial current is given by Ohm's law: I_initial = ε / R. Show more…

Consider the circuit shown below where the battery has an emf of ε = 8.2 V, the resistors have the resistances of R1=2.3 Ω, R2 = R3 = 6.6 Ω, and the capacitance of the capacitor is C=1.4 µF. The switch S is closed at t=0. The capacitor is initially uncharged. If you wait long enough after the switch is closed, at t=∞, what is the current running through R3? Please express your answer using one decimal place in units of Ampere (A).

Consider the RC circuit shown in the figure below. If the resistance of the circuit is R=2kΩ and the capacitance of the initially uncharged capacitor is C=12μF. If the emf of the battery the circuit is connected to is Ɛ=12V and the switch is closed at t=0, determine the charge of the capacitor in units of μF at the instant the current running in the circuit is at 27% of its maximum value. Express your answer using one decimal place.
