While capacitance is the primary characteristic of capacitors, the concept of “capacitor resistance” is essential for understanding their real-world performance. Capacitors are fundamental components ...

Down through the centuries in which electricity remained a natural mystery, and later a fashionable novelty, it turned up only in the form we would term today direct current (DC), that is, with ...

High-voltage circuits need strong, reliable capacitors. TDK claims that the low-resistance capacitors stay stable under stress, save space, and make devices work better. The actual appearance of the ...

Calculations of power and energy are relatively straightforward when the subject is strictly dc circuits. The situation is more complex in the ac world, however. Here are the basics of watts and ...

An ohmmeter can be used to measure the resistance of a resistor Alternatively, the resistor can be placed in a circuit and the voltage across it, and the current in the resistor can be measured. Ohm’s ...

Thermistors are used as temperature sensors, for example, in fire alarms. Their resistance decreases as the temperature increases. At low temperatures, the resistance of a thermistor is high, and ...

The “trimpot” is the standard solution to the analog designer’s occasional need to fine-tune a resistance in a precision circuit. But this old standby isn’t always available. For example, in some ...
