❓:A 12V DC power supply is connected in parallel to a 1 microfarad capacitor and a 1 kilo-ohm resistor in one loop, and a 1000 microfarad capacitor and a 10 kilo-ohm resistor in the other loop. The switch for the supply is turned on for 10 seconds and then turned off. Find the initial current in the circuit and the voltage across each capacitor once a steady state has been reached.
🔑:To solve this problem, we'll break it down into steps focusing on the initial current and the steady-state voltage across each capacitor.## Step 1: Calculate the initial current in the circuit when the switch is turned on.When the switch is first turned on, the capacitors act like short circuits, and the resistors limit the current. The circuit can be simplified into two parallel branches: one with a 1 kΩ resistor and the other with a 10 kΩ resistor. The total resistance (R_total) of the circuit can be calculated using the formula for parallel resistors: 1/R_total = 1/R1 + 1/R2, where R1 = 1 kΩ and R2 = 10 kΩ.## Step 2: Apply the formula for parallel resistors to find the total resistance.1/R_total = 1/1000 + 1/10000 = 0.001 + 0.0001 = 0.0011. Therefore, R_total = 1 / 0.0011 = 909.09 Ω.## Step 3: Calculate the initial current drawn from the 12V DC power supply.The initial current (I_initial) can be found using Ohm's law: I_initial = V_supply / R_total, where V_supply = 12V.## Step 4: Perform the calculation for the initial current.I_initial = 12V / 909.09Ω ≈ 0.0132 A or 13.2 mA.## Step 5: Determine the voltage across each capacitor once a steady state has been reached.In a steady state, capacitors act like open circuits. The voltage across each capacitor will be proportional to the resistance in its branch because the current through each branch will be determined by the voltage of the supply and the resistance in that branch.## Step 6: Calculate the current through each branch in the steady state.For the first branch with a 1 kΩ resistor, the current I1 = V_supply / R1 = 12V / 1000Ω = 0.012 A or 12 mA. For the second branch with a 10 kΩ resistor, the current I2 = V_supply / R2 = 12V / 10000Ω = 0.0012 A or 1.2 mA.## Step 7: Calculate the voltage across each capacitor in the steady state.The voltage across the first capacitor (V_C1) can be found using the formula for capacitive reactance and the current through it, but since we're looking at steady-state conditions, we can simplify by considering the capacitor as an open circuit and the voltage across it will be the same as the supply voltage times the ratio of its resistance to the total resistance. However, given the capacitors are in parallel, they will both charge to the supply voltage in steady state, not a voltage divided by the resistances as in a voltage divider with resistors.## Step 8: Realize the simplification for calculating steady-state capacitor voltage.Since both capacitors are in parallel with the power supply, in steady state, both capacitors will be charged to the supply voltage, which is 12V, regardless of the resistances in their respective branches.The final answer is: boxed{13.2}
❓:What is Alex's answer to A Clockwork Orange's repeated question, 'What's it going to be then, eh?' and how is the answer reflected in both the British and American editions?
🔑:In Anthony Burgess's novel "A Clockwork Orange," the repeated question "What's it going to be then, eh?" is a refrain that echoes throughout the book, often posed by the protagonist Alex to his droogs (friends) or by other characters to Alex. The question is a prompt for the gang to decide on their next course of action, whether it be violence, theft, or other forms of delinquency.As for Alex's answer, it varies depending on the context and the edition of the book. However, in general, Alex's response is often a proposal for some kind of violent or deviant behavior, such as "ultraviolence" or "malchick" (bad boy) activities.Now, regarding the differences between the British and American editions: the American edition of the book was published with a final chapter (Chapter 21) that was not included in the original British edition. In this final chapter, Alex, after undergoing a behavior modification treatment, begins to feel a sense of maturity and a desire to settle down, and he responds to the question "What's it going to be then, eh?" with a more positive and hopeful answer, suggesting that he may be ready to leave his violent ways behind.In contrast, the British edition ends with Chapter 20, which concludes on a more ambiguous and darker note, with Alex still embracing his violent and nihilistic tendencies. In this version, Alex's answer to the question is more open-ended and suggestive of continued chaos and anarchy.So, in summary, Alex's answer to the question "What's it going to be then, eh?" reflects the themes of violence, free will, and redemption that are central to the novel, and the differences between the British and American editions offer distinct interpretations of Alex's character development and the novel's conclusion.
