Help me understand capacitor discharging
In the capacitor, there is a drop in potential, so \$-\frac{q}{C}\$.
The problem starts for me in the part of discharging the capacitor. Now the battery acts like part of a wire, \$\varepsilon=0\$. … The top plate of the capacitor is at a higher potential. Current will flow from the top plate to the circuit in the direction of the resistor (opposite of what it was). …

Bridge rectifier peak voltage at load
Assuming the peak voltage at \$V_1\$, \$V_{1p}=9.25V\$ and ideal silicon diodes (\$0.7V\$ drop in forward bias) and the DC output in \$V_0\$ is \$5V\$. I want to find the \$V_{op}\$, peak voltage at …

Understanding/analyzing a power supply circuit
text{Led: }I_F=15mA \text{ for }V_F=2V\\\text{Voltage Regulator: For }15V<V_i<27V \rightarrow V_0=12V$$
It askes for the graph of \$V_i(t)\$, the resistance \$R_{Led}\$ and the voltage amplitude in the capacitor … 2) It seems that I have to calculate the voltage on the capacitor? …
