What is a resistor answer?

What is a resistor? A resistor is two terminal linear electronic device which is used to restrict electric current flow in a circuit. It is linear because it obeys Ohm’s law.

What are the basic responsibility of resistor?

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

What is resistor simple?

Definition of resistor : a device that has electrical resistance and that is used in an electric circuit for protection, operation, or current control.

What is resistor example?

Resistors are used for many purposes. A few examples include limiting electric current, voltage division, heat generation, matching and loading circuits, gain control, and setting time constants. They are commercially available with resistance values over a range of more than nine orders of magnitude.

What is resistor and its types?

The fixed resistor type is the most common resistor. Fixed resistors have a constant resistance value. Different resistor materials are used for fixed resistors. For all resistor types the materials influence the resistor properties like the tolerance, cost and noise.

How much voltage can a resistor handle?

The maximum power drawn by the chip through the resistor (by equation #2) will be 5 * 5 / 10000 = 0.0025 W, or 2.5 mW. That’s fine even the tiniest surface mount resistors. Manufacturers typically give a maximum voltage for a particular resistor range, such as 200V for a 250 mW resistor.

How do you classify a resistor?

Classification of resistors Fixed resistors are divided into leaded type (with lead wire) and surface mount type (without lead wire). Surface mount type includes rectangular type and cylinder type. In addition, division goes further depending on the sealing material: resin mold type and ceramic case type.

What is the Colour code for 100 resistor?

The color code for the four bands 100 Ohm resistor is brown, black, brown, gold. 4-band 100 ohm resistor color code is calculated as: 1st-band= Brown= 1 (1st digit) 2nd-band= Black= 0 (2nd digit)

What are the two types of resistor?

A resistor. Broadly speaking, resistors can be divided into two types: fixed resistors and variable resistors. As their names suggest, the resistance in fixed resistors does not change, whereas a variable resistor’s resistance could be altered easily.

What are examples of a resistor?

Laptop charger. Mobile phone charger. Fan Speed Controller [Potentiometer] All of us are familiar with the rotating knob that is used for controlling the fan speed. Lightning bulb (Carbon / Metal film) The electronics circuits in CFL, LED and other lightning lamps contain resistors.

What is the purpose of a resistor?

Resistors are the most commonly used components in electronic circuits and devices. The main purpose of a resistor is to maintain specified values of voltage and current in an electronic circuit.

What is a simple resistor?

Fixed resistors are simply basic resistors with a resistor value which cannot be changed. A variable resistor is a simple resistor, but its value may be adjusted by means of a control.
