You are trying to become a member of the Physics Olympics team. Your physics professor is training you and some other students by having you compete with each other to solve problems as accurately and quickly as you can. During one session, he springs the RLC circuit shown in Figure P32.47 (page 872) on you. Figure P32.47a shows the circuit with a battery as the energy source. The battery has an emf E and internal resistance r. He tells you the following, assuming switch S has been at position a for a long time: If only switch SL is closed, and switches SC and SR are open, and then switch S is thrown to position b, the time constant of the circuit is 1 = 0.200 ms. Switch S is returned to position a for a long time. Figure P32.47 If only switch SC is closed, and switches SL and SR are open, and then switch S is thrown to position b, the time constant of the circuit is 2 = 0.050 0 ms. Switch S is returned to position a for a long time. In Figure P32.47b, an AC source with a variable frequency has been added to the same circuit, and switch S is thrown to position b. Switches SC, SL, and SR are all open. At what angular frequency should the AC source be set so that the circuit exhibits resonance? Quick! Get to work!

A person with body resistance between his hands of 10.0k accidentally grasps the terminals of a20.0-kV power supply. (Do NOT do this!) (a) Draw a circuit diagram to represent the situation, (b) If the internal resistance of the power supply is 2000 , what is thecurrent through his body? (c) What is the power dissipated in his body? (d) If the power supply is to be made safe by increasing its internal resistance, what should the internal resistance be for the maximum current in this situation to be 1.00 mA or less? (e) Will this modification compromise the effectiveness of the power supply for driving low- resistance devices? Explain your reasoning.

Please answer the problem below

If the switch (S) in the figure is closed for a very long time, what is the charge on the capacitor?  Use an emf of  20 V, R1 = 100 Ω and  C1 = 20 μF.

The figure below shows a circuit that consists of two identical emf devices. If  R1 = R2 = R  and the switch is closed, find an expression (in terms of R and ) for the current I that is in the branch from point a to b. (To represent, use E.)

In the circuit shown at the right, RA is identical to RC, and RB is twice A and C.  Ra = Rc = 1/2Rb The current through each resistor is labeled i. Let the potential drop across resistor A be called deltaVA and so on. The battery provides an EMF = V0.    ANSWER WITH THE CHANGE WHERE EVERYTHING IS NOW EQUAL TO EACH OTHER*   Which of the following must be true of the currents in the circuit?  iA = iB only  iA = iC only  iA = iB = iC  iA = iB + iC  iA = iB - iC  None of these    What is the relationship between ib and ic?  iB = ⅓ iC iB = ½  iC iB = iC iB = 2 iC iB = 3 iC None of these    Which of the following are true about the magnitudes of the potential differences in the circuit? Select all that apply VA = VB VB = VC VA = V0 V0 = VB + VC V0 = VA + VB V0 = VA + VC   Which of the following is the correct relationship between deltaVA and deltaV0.  VA = V0 VA = 1/2 V0 VA = 1/3 V0 VA = 2/3 V0 VA = 3/5 V0

An uncharged capacitor and a sequence of resistors are connected as shown in the figure below. After the switch is closed, find: a. The time constant of the RC circuit b. The maximum charge on the capacitor c. The charge on the capacitor 2 ms after the switch is closed

Consider the circuit below. Assume that the capacitor is initially uncharged. V₁=24 V R = 10 ΚΩ : R2 = 30 ΚΩ www Description of Image a. What is the initial current through resistor R₂ when the switch is closed (t = 0)? Current through R₂ at t = 0 is 8 O = 0.8 mA. Hint O O O C₁ = 10 μF b. What is the current through resistor R₂ when the capacitor is fully charged, long after the switch is closed (t→ ∞)? Current through R₂ as t→∞ is 6 O = 0.6 mA. c. What happens if the switch is opened after it has been closed for some time? Choose the most correct statement below. Current flows through C₁ but not R₁ or R₂. Current flows through V₁, R₁, R2, and C₁. Current flows through R₁ and C₁ but not R₂. No current flows anywhere in the circuit. Current flows through C₁ and R₂ but not R₁. Current flows through R₁ and C₁ but not R₂. X In time t = initial value. d. If the switch has been closed for a time period long enough for the capacitor to become fully charged, and then the switch is opened, how…
