The output of an electric fencer is a high voltage pulse of DC voltage.
You can use a DC ammeter.
7.5v 500mA Dc charger
In a clipper circuit, the diode is used in series to selectively cut off portions of the input signal, allowing only certain voltage levels to pass through while blocking others. In contrast, a clamper uses the diode in parallel to shift the entire waveform up or down, ensuring that the output signal maintains its shape while altering its DC level. This configuration allows the clamper to add a DC offset to the AC signal without clipping any part of it.
The output from a DC generator is not pure DC due to the presence of ripple voltage, which results from the mechanical commutation process. As the generator's rotor rotates, the commutator segments switch connections, leading to fluctuations in voltage. While the output is predominantly direct current, these variations can cause it to deviate from a perfectly smooth DC signal. Additional filtering may be required for applications needing a more stable output.
There is no transformer used in PC power supply. There is rectifier used to rectify or convert AC input voltage into DC output voltage.Transformer based rectifier produces some spikes at the output DC voltage, hencethey uses SMPS (Switch Mode Power Supply) to avoid spikes to the output DC voltage and get a smooth DC voltage.
Battery chargers have a 12v DC output.
I would use my multimeter to read the output.
An alkaline battery's output is DC as is any battery.
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.

There are several ways. You can simply use a resistor to have a drop of 20v across it. You can use a diode with its negative edge connected to a 12 v supply and the positive edge as your input. When your input crosses 12 volts, the diode is turned on and causes a short circuit. If the output is also connected to the positive end of diode then it will never see a voltage above 12 volts. However, a lesser voltage is visible at the output then. This is somewhat the concept behind the clipper circuit made from diode. You can also convert this 32v dc to a digital value and then while converting it back to a 12v dc through DAC (here your DAC should ideally give a constant dc output).

megger are available in ac &dc
A battery by itself will only supply DC output. You would need a method to convert DC to AC, such as an inverter, in simplified terms: an electronic circuit which has an oscillator to create the desired frequency then amplifies it to the desired magnitude output. Another way, which I don't know if used anymore, is a motor-generator set. A DC motor's shaft is connected to an AC generator's shaft, and the output is taken from the AC generator.
AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.
