Consider the circuit shown in the figure. Before the two capacitors were inserted into the circuit, they were fully charged by a 23.0 V battery. Imagine that the switch is now closed. 3.00 µF 2.00 uF 500 2 (a) After a time interval of 2.20 ms, what is the value of the remaining charge (in µC) on the 3.00 µF capacitor? µC (b) After a time interval of 2.20 ms, what is the value of the remaining charge (in µC) on the 2.00 µF capacitor? | µC (c) What is the current (in mA) in the resistor at this time? mA

Challenging Diodes problem I'm stuck on: In the circuit below, Vz = Vz0 = 5 v. rz = 0 and Iz,min = 0. What is the current through the diode, voltage drop measured V1 and is the diode on in each case? a) Vin = -5  b) Vin = 5  c) Vin = 15

Please solve in 25 minutes, please

The circuit below with an ideal diode is used to charge a 12 V battery. vin is a sinusoid with 24 V peak amplitude: vin = 24 sin(⍵t) a) For how long does the diode conduct within each cycle: 1/2 of the cycle time, 1/3 of the cycle time, ¼ of the cycle time, or 1/5 of the cycle time?  b) Find the peak value of the diode current and the maximum reverse-bias voltage that appears across the diode.
