- The circuit in Figure has been connected for a long time. If the battery is disconnected, how does it take the capacitor to discharge to 1/20 of its initial voltage? Take R₁ = 2.00 Q, R₂=4.00 Q, R3-7.00 Q, R4 = 2.00 Q and C= 5.00 uF and ε = 14.0 V. (Your result must be in us. Include 2 digit after the decimal point and maximum of 2% of error is accepted in your answer.) E R₂ R₂ BAFor the following circuit, Vsrc=1.5 V and Rload%3D225 Q. What is Is? Is +. Vsrc VR Rload 30 mA 9 mA 6.67 mA 40 mVSince V=12V, C1 = C4 = 2uF, C2 = 4uF, C3 = 1uF in the circuit in the figure, what is the charge (in uC) on the capacitor C4?
- For R1=8000 Q, R2=9000 Q, R3=7000 Q, R4=8000 , C1=0.002 F, C2=0.004 F & 1=0.002 A in the shown circuit, obtain the energy stored in each capacitor under dc conditions. C2 R4 I1 ER3 ŽRI C1= Energy stored in C1 (in Joule)= Energy stored in C2 (in Joule)= wwExplain how you would this equation in basic termsThe parallel combination of R2 and C2 in the circuit shown represents the input circuit to a cathode-ray oscilloscope (CRO). The parallel combination of R1 and C1 is a circuit model of a compensating lead that is used to connect the CRO to the source. There is no energy stored in C1 or C2 at the time when the 10 V source is connected to the CRO via the compensating lead. The circuit values are C1=4 pF, C2=16 pF, R1=1.25 MΩ, and R2=5 MΩ. 1. a) Find vo. 2. b) Find io. 3. c) Repeat (a) and (b) given C1 is changed to 64 pF.

In the cimuit (b) 20 uC (c) 25 uC (d) 48 uC www wwwPlease zoom it this questionIn the diagram below, the switch S has been closed for a long time. A) What is the output voltage Vout? What is the charge on the capacitor? b) The switch is opened, so the output voltage increases. What is the time constant that describes the charging of the capacitor in terms of R and C? c) When Vout reaches 10 V, the switch closes and the capacitor begins to discharge. What is the time constant that describes the discharging in terms of R and C? Hint: Apply Kirchhoff's Rules to both loops and the sum of the currents at the junction above the capacitor in the diagram, and use I=dq/dt. If the switch opens when Vout reaches a lower value, say 5V, the capacitor will charge again, and thus one can cycle the voltage with a time constant determined by the circuit: this demonstrates the principle of operation of an electronic timer. 4R S 15 V Vout R
