Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

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, in a series ...

Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...

Despite how useful multimeters are, there are a lot of limitations you just don’t think about because they’re the way electronic measurement has always been done. Want to measure voltage and current ...

There are many reasons why one would want to measure voltage and current in a project, some applications requiring one to measure mains and even three-phase voltage to analyze the characteristics of a ...

One application that uses a precision power supply and DMM involves characterizing the current drawn by a device or circuit board at different voltage levels. Figure 1 shows a typical setup. Engineers ...

When two inverters are connected in parallel, they share the same input (battery or solar supply) and output (AC load). This ...

Another important concern is the balance of currents that flow in multiple strings. We know that two or three strings of LEDs will have different combined forward voltages. The LED driver will deliver ...

Capacitors often are connected in parallel in power electronics to decrease high-frequency ripples, current stress, decrease power dissipation, and operating temperature, as well as to shape ...

Forbes contributors publish independent expert analyses and insights. Technology journalist specializing in audio, computing and Apple Macs. Plugable is one of those fascinating companies that make ...
