Frequently Asked Questions

What are the types of resistance?

Thermistors. Thermistors are resistors of which the resistance changes significantly when temperature changes. Different thermistor types exist, the two most common types are the NTC and PTC thermistor. NTC thermistors decrease in resistance when the temperature rises, while PTC thermistors increase in resistance when the temperature rises.

What is the meaning of resistance?

Resistance is defined as a refusal to give in or to something that slows down or prevents something. An example of resistance is a child fighting against her kidnapper.

How are voltage, current, and resistance relate?

Voltage, Current, and Resistance Voltage. Voltage is an electrical pressure, which forces the electric charges (electrons) to move in an electrical circuit. Current. Electric current is the number of electrons flowing through a point in a circuit. Consider a circuit, which is marked 'A' at a point. Resistance. Resistance, as the name suggests, provides the resistance to the electrical current. It always tries to stop the current from flowing. More items...
