3-3 rectification? A d'Arsonval meter movement with a full-scale deflection current rating of 1 mA and an internal resistance of 500 2 is to be used in a half-wave rectifier ac voltmeter. Calculate the ac and dc sensitivity and the value of the multiplier resistor for a 30-V rms range.

The four diodes used in a bridge rectifier circuit have forward resistances which may be considered constant at 1 ohm and infinite reverse resistance. The alternating supply voltage is 220 V r.m.s. and load resistance is 580 ohm. Calculate (i) mean load current and (ii) power dissipated in each diode.

In the circuit of the following figure, the input voltage Vs is 15 volts rms with a frequency of 60 Hz, R equals 150 Ohms and C equals 100,000 Pico Farads. The diodes are Germanium (Vd = 0.2 volts) and the Zener diode is 12 volts. a) The magnitude of the ripple voltage at Cb) The Magnitude of the Peak Inverse Voltage (PIV) for D1 and D2.

A half-wave rectifier is needed to supply 15-V dc to a load that draws an average current of 250 mA. The peak-to-peak ripple is required to be 0.2 V or less. What is the minimum value allowed for the smoothing capacitance?

Please help me to understand this question. It's hard and challenging.

I need a diagram of a circuit by the transform and rectification block, using the bridge rectifier circuit (2W10). It can be a source of any value. You don't need to do any calculations, just a drawing of how this circuit will look, please.
