What is a Shunt Resistor?Shunt resistance definitionA shunt resistor is a high-precision resistor that uses a very low ammeter resistance to measure the flow of current through a circuit. It is the resistance of a conductor in parallel with a circuit. Because of its particularity, it is generally used in precision electronic products. The smaller the resistance value of the shunt resistance, the more obvious the shunt effect.Shunt resistance characteristic Good structure High stabilityResistance

What is a Pull-up Resistor?Pull-up resistance definitionA resistor used in an electronic circuit to ensure the known voltage state of a signal.Basic structure of pull-up resistorWorking principleOn the wire to which the pull-up resistor is connected, if the external component is not enabled, the pull-up resistor "weakly" pulls up the input voltage signal. When the external component is not connected, the external "looks" high impedance to the input. At this time, the voltage at the input port ca

What is Light Dependent Resistor?Photoresistor definitionPhotoresistor is a kind of semiconductor device based on internal photoelectric effect, and its resistance value depends on the change of incident light intensity. With the increase of incident light intensity, the resistance value of photoresistor decreases, the incident light weakens, and the resistance value of photoresistor increases. The photoresistor has no polarity, and an external voltage in any direction is applied at both ends wh

What is a Variable Resistor?Variable resistor definitionResistor whose resistance can be adjusted as needed. It is a common component in electronic circuits that allows current or voltage to be adjusted according to Ohm's law.Basic structure of variable resistorA variable resistor usually has three terminals: two fixed terminals at the end of the resistance track and one removable terminal (cursor). Depending on how the terminals are connected to the circuit, a variable resistor can be used as a

What is an Electrical Resistor?A resistor is a passive component in a circuit which provides resistance to the flow of current. There are many different types of resistors. These resistors vary in their construction, power dissipation capacities, and tolerance to various parameters (such as temperature and light). The types of resistors include: Carbon Composition Resistor Thermistor Wire Wound Resistor Metal Film Resistor Carbon Film Resistor Variable Resistor Varistor Light Dependent Resistor

What is a Bleeder Resistor?A bleeder resistor is a standard resistor connected in parallel with the output of a high-voltage power supply circuit for the purpose of discharging the electric charge stored in the power supply’s filter capacitors when the equipment is turned OFF. This is done for safety reasons.If someone accidentally touches during the service of equipment in the OFF state, there may be a chance to get shocked even if the device is in OFF condition. Hence, it is necessary to disch

What is a Ballast Resistor?A ballast resistor is defined as a resistor inserted into a circuit to minimize current. Ballast resistors also help to avoid over-current faults in a circuit. An “electric ballast” is a more general term used to refer to an electrical device used to maintain a circuit’s stability by limiting the value of current and voltage. Electric ballasts can be resistors, capacitors, inductors, or a combination of these.Ballast resistors are able to change resistance with the cur

What is an Electrical Resistor?A resistor (also known as an electrical resistor) is defined as a two-terminal passive electrical element that provides electrical resistance to current flow. Resistance is a measure of the opposition to the flow of current in a resistor. The larger a resistor’s resistance, the greater the barrier against the flow of current. There are many different types of resistors, such as a thermistor.In an electrical and electronic circuit, the primary function of a resistor

What is a Shunt Resistor?A shunt resistor (or shunt) is defined as a device that creates a low resistance path to force most of the electric current through the circuit to flow through this path. In most cases, a shunt resistor is made up of a material having a low-temperature coefficient of resistance, giving it a very low resistance over a wide temperature range.Shunt resistors are commonly used in current measuring devices called “ammeters”. In an ammeter, the shunt resistance is connected in
