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 ...

Dielectrics are of two types: (i) Non-Polar Dielectrics: When the centre of positive charge coincides with the centre of negative charge in a molecule, e.g., Nitrogen, Oxygen, CO 2 etc. (ii) Polar ...

What capacitance do you get when you buy a multilayer ceramic capacitor? It might sound like an odd question but the actual answer is down to dielectric type, design and operational conditions which ...

A capacitor measured with a $100 handheld multi-meter can give a substantially different result than the same capacitor measured with a $10,000 LCR meter. That same capacitor measured with two ...

General decoupling applications require capacitors with a combination of high capacitance and low reactance (i.e., low equivalent series resistance [ESR] and equivalent series inductance [ESL]) in the ...

Printing electronic circuits will usher in a new era in electronics. With ion gel dielectrics, unprecedented transistor performance and speeds at low voltage can be demonstrated. The next wave in the ...
