what happens with the voltage dissipated by a resistor in an RC CIRCUIT ? WHY ?
explain the answer clearly, each of the questions
Step by step
Solved in 2 steps with 2 images
- If you wanted to modify an RC circuit so that it would take the capacitor twice as long to discharge, how could you do that? (Hint: Remember that RC is the amount of time it takes to discharge to 37% of the original voltage.) Make the capacitance (C) half as large Make the resistance (R) twice as large Make the resistance (R) half as large Make the resistance (R) four times as largeIn RC Circuit, the voltage across the resistor decreases as the capacitor charges. Explain the reason for this behavior.A 71 Ohm resistor and 1.047 F capacitor are connected in series to a 11 V DC voltage source (RC Circuit). What is the half-life that characterizes this RC Circuit?
- In RC Circuit, the current decreases exponentially with time as the capacitor charges. Explain the reason for this behavior.In an RC series, we want to measure a voltage that displays the behavior of the current in the circuit. How must the resistor and capacitor be connected to the signal generator and how must the oscilloscope be connected? Write a short essay answering these questions. Then explain why the circuit must be arranged this wayIn a series RC circuit, what will the graph of current versus time look like for the condition where the capacitor is initially uncharged at time=0 and then connected to a battery. Explain precisely; you do not need to include a graph.
- Many people have the mistaken impression that current is used up around a circuit. In a series circuit, for instance, is it true that the current decreases as it passes through the resistors? What actually happens?If the resistor in a RC circuit is replaced by a resistor with larger resistance, what happens to the time to fully charge the empty capacitor in the RC circuit? The time increases. The time decreases. The time does not change. It cannot be determined4. (a) Briefly explain what happens to the voltages and currents when you connect a battery to a DC RC circuit where R and C are in series with the battery. (b) Briefly describe what happens to the voltages and currents when the battery is subsequently removed and there is just R and C in series. NOTE: Consider voltages for each circuit element.
- A circuit of capacitors connected in parallel is plugged in a 120 V outlet. What can you tellabout the voltage on each capacitor and current in each capacitor?An RC circuit has a resistor of 1000 92 -resistance. Its time constant is 1 s, what is the capacitance of the capacitor? OA) 10 F OB) 1 F OC) 0.1 F OD) 100 F OE) 1 mFIn a series RC circuit composed of a resistance R, a capacitor, and an emf source, the energy stored in the capacitor decreases with time as the capacitor discharges. After how many time constants is this stored energy one-fifth its initial value? A) 0.55 B) 1.04 C) 0.80 D) 0.90 E) 0.35
