A capacitor is charged to an initial voltage Vo - 7.6 V. The capacitor is then discharged by connecting its terminals through a resistor. The currentI (t) through this resistor, determined by measuring the voltage VR(t)- I(t)R with an oscilloscope, is shown in the graph. 85 80 75 70 65 60 50 45 40 35 30 25 20 15 10 ms) 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 Part...
A 270-kilo-ohm [kΩ] resistor and a 0.4-microfarad [μF] capacitor rated at 210 volts [V] are connected in series, meaning that all of the current through the resistor enters the capacitor. (a) Assuming that the capacitor is initially fully discharged and that a constant voltage of 5 volts [V] is maintained across the resistor, how long, in units of seconds [s], can this circuit operate before the voltage rating of the capacitor is exceeded? The circuit can operate for _...
1)A 3300 F capacitor is connected in series with a 50 k resistor to a 64 V voltage source. At t=0, the charge on the capacitor is zero. Initially, is almost zero, while is almost 64 V. The current is constant over time. While the voltage across the capacitor changes, the voltage across the resistor remains constant. The voltage across the capacitor is always 64 V. Initially, is almost 64 V, while is almost zero. As the charge on the capacitor increases over time, so does the current through the circuit.2)At what time is the...
