What else can I help you with?
A can be used to reduce the current in a circuit?
A resistor.
What is need of capacitor and resistor in circuit?
because without using capacitor or resistor in a circuit,it cant be complete.Resistor is used to protect the circuit by giving a certain amount of voltage.Capacitor is used to charge and discharge purpose.
What is the need of preset resistor in ldr circuit?
A preset resistor, or variable resistor, is used in an LDR (Light Dependent Resistor) circuit to adjust the sensitivity of the circuit to light levels. By varying the resistance, it allows fine-tuning of the threshold at which the circuit responds to changes in light intensity. This is particularly useful in applications like light sensors or automatic lighting systems, where precise control over activation levels is desired. The preset resistor helps ensure optimal performance and responsiveness of the LDR circuit.
What is the lifespan of a resistor?
A resistor doesn't deteriorate with age, and has no particular 'life-span', as long as it's used properly. -- A resistor in a box on the shelf, or in a circuit where it stays cool, will last indefinitely. -- A resistor in a circuit where it's forced to dissipate enough power to make it hot may change its resistance value permanently, but will continue to operate. -- A resistor in a circuit where it's forced to dissipate even more than that, to a ridiculous extreme, may melt or explode. When that happens, it's the end of the resistor's life-span. But it wasn't the resistor's fault.
What is the meaning of resistor?
Resistors are one of the three basic electronic components. They restrict the flow of current in an electrical circuit. Fixed resistors have a fixed value of resistance, and are used in almost every electronic circuit for lots of different reasons.
A can be used to reduce the current in a circuit?
A resistor.
What does the variable resistor do in a circuit?
It is used to vary the voltage/current flow in a circuit.
What can be used to reduce the current a circuit?
A resistor.

What is a function of a resistor in a fire alarm circuit?
A resistor in a sensor circuit is used as a simple way to monitor the function of the circuit. The resistor has a calibrated and known voltage drop and current while the circuit is "normal". If there is a short-circuit, or an open-circuit, the voltage and current will change and trigger the trouble alarm.
What does a pre-set resistor do in a circuit?
A preset resistor is used in some circuits to change the resistance. The preset resistor enables the circuit to be more or less sensitive thereby altering the resistance.
Where is ballast resistor on Dodge Grand Caravan sport 2002?
It does not have a ballast resistor, those were used for ignition systems 30+ years ago. It does have a blower motor resistor that is located behind the glove box.It does not have a ballast resistor, those were used for ignition systems 30+ years ago.

What is a device that resists the flow of electricity in a circuit?
A resistor is a device that resists the flow of electricity in a circuit. It is used to control the amount of current flowing through the circuit by providing a specific amount of resistance.
What is the roll of bleeder resistance in LC filter circuit and what will happen if the bleeder resistor is not used in circuit?
jgfkf
What are devises run by electrical energy represented as resistors in a circuit?
Do not confuse 'resistance' with 'resistor'. 'Resistance' is a quantity, wheras a 'resistor' is a circuit component. In schematic diagrams, the 'rectangular' (European) or 'zig-zag' (US) circuit symbol represents resistance, not a resistor. The circuit symbol, therefore, is used to represent anyresistive device.
What is a resistor block?
It is a resistor or a group of resisters used to control the flow or current in a circuit. Like the resistor block in a car controls the speed of the a/c blower.
What is a tool that is used to control the current that goes through a circuit called?
resistor
