Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

An Apple patent application discovered on Thursday reveals that the company is actively investigating wireless charging for its line of portable devices, but proposes to use the technology in a ...

IT was originally supposed that separating contacts in low-voltage, low-inductance circuits interrupted the current without arcing provided the supply voltage was lower than the ionization potential ...

Some operational amplifiers (op amps) have an inductive open-loop output impedance, which can be more complex to stabilize than op amps with resistive output impedances. One of the most common ...

Few electronics design areas benefit as much from the use of inductive components as the avionics industry, yet many people feel uncomfortable using these parts, or fail to see their true value.

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

For whatever reason, cell phone companies really don’t seem to care about giving you a good battery for your phone. Here’s a great hack if you happen to have a purse — turn it into an inductive ...
