What is the resistance of an airbag?
1 Answers
The resistance of an airbag is generally between 2 to 6 ohms. The resistance of the igniter inside the SRS airbag component is typically 200 ohms, while the collision sensor usually has a resistance of 3.2-3.8 kiloohms. Introduction to Resistance: Resistors are commonly referred to simply as resistance in daily life. They are current-limiting components. When a resistor is connected in a circuit, its resistance value is fixed, usually with two pins, and it can limit the current flowing through the connected branch. A resistor with an unchangeable resistance value is called a fixed resistor. A resistor with a variable resistance value is called a potentiometer or a variable resistor. Principle of Resistance: An ideal resistor is linear, meaning the instantaneous current through the resistor is proportional to the applied instantaneous voltage. A variable resistor used for voltage division has one or two movable metal contacts pressed tightly against the exposed resistor body. The position of the contacts determines the resistance value between any end of the resistor body and the contact. The terminal voltage and current have a definite functional relationship, representing a two-terminal device that converts electrical energy into other forms of energy. It is denoted by the letter R and measured in ohms. Actual devices such as light bulbs, heating wires, and resistors can all be represented as resistor components.
