For use with a 9 volt battery, the incandescent lamps can be replaced with a regular LED and 680 ohm resistor and the output transistors can be replaced with small signal transistors (2N3904 or 2N3906). The total current drain will be about 25 mA with the LED lit, and 15 mA standby when the LED is off. In the 'experiment' shown in Lecture 14-15, a 6-volt 0.5A cycle lamp connected to a fresh PP3 burnt for about 40 minutes. This suggests that the battery could provide approximately 40/60 x 0.5 Ah, or about 330 mAh. In practice, batteries can provide more mAh when discharged slowly than if overloaded, as in this case. To measure resistance, switches arrange for a small battery within the instrument to pass a current through the device under test and the meter coil. Since the current available depends on the state of charge of the battery which changes over time, a multimeter usually has an adjustment for the ohm scale to zero it.

Feb 14, 2008 · If you connected a 9 volt battery to this scale, you would get 9 on the display, in the 20 volt range, you might get 9.45 volts. The "m" with the 2000, and 200 scales are Milli-volts. The 2000 Milli-volts, by the way will measure a 1.5 volt cell (battery) because full scale value of that scale is actually 2 volts. Most replacement microwave oven diodes are rated 12 to 15 KV PRV at .5 A. A PRV of around 8 KV is actually required even for a small oven. Here is why: Until the magnetron heats up and starts conducting in its forward direction, what you have is a half wave rectifier/filter formed by the HV transformer secondary, the HV diode, and the HV capacitor.

This little circuit uses a LM317 variable voltage regulator to adjust the input voltage down to +9 volt, or whatever else you need. Just a solid basic circuit without bells and whistles. You can do with a 10uF capacitor for C1 if your battery is close to this circuit. If it is located more than 3 feet increase the value to 100uF or above.
Make certain a) all power to the circuit is OFF and b) no voltage exists at the diode. Voltage may be present in the circuit due to charged capacitors. If so, the capacitors need to be discharged. Set the multimeter to measure ac or dc voltage as required. Turn the dial (rotary switch) to Diode Test mode ( ).
