You need to know how to measure the current that flows through a component in a circuit and the voltage across it. The ammeter must be connected in series with the component – remember ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but ...

Current is a measure of how much ... so you may hear or see ‘voltage’ instead of ‘potential difference’. A circuit diagram showing a voltmeter in parallel with a lamp When two components ...

The flyback transformer is custom-wound with copper wire to achieve the necessary inductance for plasma generation. Its AC output is rectified to DC using a high-voltage microwave diode, as DC is ...

High voltage circuits often don’t have much spare current for measuring purposes. R1 was also selected such that there wouldn’t be a problem with leakage over its surface. In my case R1 is ...

Do you want to power a group of lighting LEDs? Here we present a handy solution to provide extremely accurate and stable ...

In GPS and wireless communication, a constant voltage is vital at a desired network branch. But how to achieve that? One can take a circuit, for instance.

Every electrical current generates a magnetic field, so a non-contact voltage tester can detect ... “Start by testing on a known live circuit, then on a dead one, and then finally back to ...
