Learn how engineers design electrical circuits by calculating the voltage, current and resistance of electrical components.

Learn how to measure current and voltage and the advantages of parallel circuits.

In these test circuits, adding AC source Vin in series with one of the power-supply voltages generates the DC + AC test signal. The op amp is placed in a standard unity-gain buffer configuration with ...

How Long Is Your Spark? The simplest way to measure high voltage is by spark length. If your circuit has a spark gap then when a spark occurs, that’s a short-circuit, dumping all your built up ...

Don’t get zapped when buying a new high-voltage DC power supply. Understand the specifications first. Lasers, linear accelera-tors, X-ray machines, defibrillators, radar, and ...
