A complicated RC circuit is shown in ( Figure 1), with R₁ = 15Q₁R₂ = 20, R₂ = 40₁C₁ = 16µF, 1 2 1 and C₂ = 12μF. The capacitors are 2 initially uncharged, and the switch is initially open. Figure 1 of 1 A.) when the switch is first closed, what is the current through R2? B.) after the switch has been closed for a long time how much energy is stored on the capacitors(the total energy on the two of them)? A complicated RC circuit is shown in (Figure 1), with R₁ =15, R2 =20, R3 =40 2, C₁=16 μF, and C₂ =12 F. The capacitors are initially uncharged, and the switch is initially open. Figure R₁ < 1 of 1

Problem 8:   Consider a circuit shown in the figure. Ignore the internal resistances of the batteries. A) Express the current I1 going through resistor R1 in terms of the currents I2 and I3 going through resistors R2 and R3. Use the direction of the currents as specified in the figure.  B) Write the equation of potential change in loop EBAF in terms of the circuit elements. C) Write the equation of potential change in loop DCAF in terms of the circuit elements.  D) Solve the three equations to get I3 as expression NOT a numerial value

The capacitor in the circuit shown is fully charged by a 24 V battery. The switch is closed at t = 0. At sometime after the switch is closed, the voltage across the capacitor is measured to be 10 V. What is the current in the circuit at this time, in Ampere? C = 3.0 µF, and R = 2.0 02. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Cil

In the circuit below, it is known that R1 = 10 kΩ, R2 = 15 kΩ, and C = 0.4 μF, and a battery with an Emf of 20 Volts. Initially, the connector (switch) is connected for a long time until it reaches a steady state. Then the switch is disconnected/opened at t = 0. What is the current flowing in resistor 2 at t = 4 ms?
