I'm studying the electrical section. Can you help?
1) In the circuit below, plot the waveform of the diode yoltage and the waveform of the current passing through R 1 in scale.
2) A rectifier circuit with a sinusoidal wave and a peak value of 35v will be designed. It is desited to use four ideal diodes in the circuit to be designed, and design the circuit by calculating the load value
so that the load current is 5 A. Draw the waveform of the voltage falling on the charge.
