If there is no voltage, there is a break in the circuit between the battery and the + terminal. Possibly the ballast resistor is faulty. Checking the coil To check the coil, wedge the points open and connect a
I wouldn't use the output of a class D amp as input for another amp since class D amps got a high THD. But you could try it to check if it would be ok for you, it's not a HiFi application :-) Add a voltage divider (output about 0.5-1V) and a small pass capacitor....
the filament is electrified and provides high resistance to the current, which causes the filament to glow inside a confined glass globe. This creates light, but also a lot of heat. With fluorescents, the electrical current is directed through a sort-of transformer called aballast, then...
How to Check Fuses A blown fuse can be annoying, but it actually helps prevent electrical damage and fire. Fortunately, fuses are inexpensive and easy to replace. If the power’s out in your home or car, you should be able to check the fu... ...
