  • The role of a resistor in a circuit

    2019-09-25
    Resistor is made of some materials which hinder the current. It is one of the most basic and commonly used electronic components. Resistor has many uses in the circuit, which can be summarized as reducing voltage, distributing voltage, limiting current and providing necessary working conditions (voltage or current) to various components. For convenience of expression, resistor is usually referred to as resistance.

  • What is the difference between a resistor and a resistor

    2019-09-25
    What is a resistor? A resistor is a kind of current limiting element that we are very familiar with. I believe that many friends have some understanding of it no matter in the physics textbooks of junior high school or in the production and life now. So, what is a resistor, let's follow the small series to understand the difference between resistors and resistors, let's learn!
