Find the voltage drop across the resistors. Each diode has a turn-on voltage of 0.7V.  VR1 = ? VR2 = ? VR3 = ? VR4 = ?

You are an electrician working on an overhead crane. The crane uses a large electromagnet to pick up large metal pipes. The magnet must have a minimum of 200 VDC to operate properly. The crane has an AC source of 240 V. You are given four diodes that have a peak voltage rating of 400 V each. These diodes are to be used to form a bridge rectifier to convert the AC voltage into DC voltage. Is the voltage rating of the diodes sufficient? To the nearest volt, what will be the DC output voltage of the bridge rectifier?

Please answer in typing format

The diode has a forward voltage of 0.7 V. V is a variable DC source, R1 = 11KQ and R2 = 6KQ. in R1 Vin R2 V out If V, is increased from zero, at what value of V, in volts will the diode start to conduct? in

For the circuit in the figure, let V input = 8V, Ri = 12ohms, RL = 10ohms, and VZ = 3.3V. Determine the voltages and currents of the resistors and the current of the zener diode.
