Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...
In this circuit the 555 timer is used in a novel way, as a voltage controlled switch.The old and omnipresent NE555 can be very good at something it was not meant for: driving relays or other loads up ...
Measuring extremely high dc voltages of 10 kV or more usually requires a suitably equipped high-voltage ohmmeter or a digital multimeter and high-voltage divider, along with the proper safety ...
