Yes, an eraser can act as a resistor in a circuit, albeit with limited and inconsistent performance. It has some resistance due to its composition, which is primarily rubber and other materials, allowing it to impede the flow of electric current. However, its resistance values are not well-defined, making it unsuitable for precise applications in electrical circuits. Its use as a resistor would be more of an experimental or educational demonstration rather than a practical solution.
A resistor.
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
Scroll down to related links and look at "Symbols for a resistor".
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 does a resistor in an ampliflyer circuit
A resistor is used to reduce current flow, and will also act to lower voltage levels in a circuit. It also dissipates heat.
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
Any part of a circuit that has a voltage drop across it is a resistor.
A resistor.
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
It is used to vary the voltage/current flow in a circuit.
A resistor reduces the flow of current in an electrical circuit, which in turn affects the voltage across the resistor.
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total. By removing a resistor the total current will lower. If you short out the parallel circuit as suggested it will take out the fuse that should be protecting the circuit.AnswerShorting-out a resistor in a parallel circuit, will act to short out the entire circuit, therefore, significantly increasing, not lowering, the current! And, as the previous answer indicates, this short-circuit current will operate any protective devices, such as a fuse.In a parallel circuit current does not lower but it will be increase if shorting-out one resistor in the two resistor parallel circuit, the circuit will become very low resistive and the larger current will flow through the short path.
Equivalent Resistor
resistor
To connect a variable resistor to a circuit, identify the two terminals of the variable resistor. Connect one terminal to the input or output of the circuit where you want to adjust the resistance. Connect the other terminal to either the ground or another reference point depending on the circuit's design. Ensure that the resistance value on the variable resistor is adjusted as needed for your circuit application.
