What is a resistor
Resistors are generally referred to as a resistor in daily life.Is a current limiting element, after the electrical blocking is in the circuit, the resistance of the resistor is fixed, which is generally two pins, which can limit the current size of the branch therebetween.The resistance value cannot be changed, referred to as a fixed resistor; the resistance is variable, referred to as a potentiometer or variable resistor.
What is a high power resistor
High power resistance mainly refers to a higher power resistance than conventional resistors.The size of the power is relative to the convention, is not an absolute power or more.
What is the role of high power resistor?
The role of high-power resistors is usually current limiting and voltage pressure, generally used in power supplies, and the balanced output resistors for power amplifiers, and often as loads in circuit load tests.
