Resistors are used in circuits to limit the flow of electric current, ensuring that components operate within their specified voltage and current ratings. They help control the voltage drop across components, divide voltages, and protect sensitive devices from excessive current. Additionally, resistors can be used for signal conditioning, biasing active devices, and creating specific circuit functions like filters and oscillators. Ultimately, they are essential for maintaining circuit stability and functionality.
What else can I help you with?
Can you use a 91ohm resistor in place of 100ohm resistor?
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.
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.
A can be used to reduce the current in a circuit?
A resistor.
What is the function of a variable resister in an electrical circuit?
A variable resistor usually has three terminals, one of which is connected to the 'wiper' by which means its resistance is measured. By using all three terminals, we can control the potential difference in a circuit. When used in this way, we call the variable resistor a 'potentiometer'. By using two of the three terminals, one of which must be connected to the variable wiper, we can control the current passing through circuit. When used in this way, we call the variable resistor a 'rheostat'.
What is series dropping resistor?
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
What work resistor?
when a resistor is connected in a circuit it drop some voltage across it.when a circuit have large input voltage then by using a resistor of suitable value we get the desired voltage.
How is the energy dissipated by the resistor in an RC circuit calculated?
The energy dissipated by a resistor in an RC circuit is calculated using the formula: Energy 0.5 C V2, where C is the capacitance of the circuit and V is the voltage across the resistor.
Can you use a 91ohm resistor in place of 100ohm resistor?
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.

Which device controls the flow of electrons in an electric circuit?
Flow of electricity in a circuit is controlled by using '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.
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
What parts of a circuit acts as a resistor?
Any part of a circuit that has a voltage drop across it is a resistor.
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.
How do you know if the resistor is defective?
To determine if a resistor is defective, you can measure its resistance using a multimeter. If the measured resistance significantly deviates from the resistor's specified value (indicated by its color code), it may be faulty. Additionally, visual inspection for physical damage, such as burns or cracks, can also indicate a defective resistor. If the resistor is part of a circuit and the circuit is not functioning properly, it may be worth testing the resistor as a potential cause.
Does a resistor reduce current or voltage in an electrical circuit?
A resistor reduces the flow of current in an electrical circuit, which in turn affects the voltage across the resistor.
