Highly inductive load as a constant current source?

An inductor is a device that resists a change in current. The equation is di/dt = v/L. This means that inductors are current sources, and given a sufficiently large inductor, in comparision to the circuit, it is a constant current source.


What is an electrical part called a resistor?

It is a component or substance which reduces the flow of electricity in a circuit. Their will be one in your mobile phone charger to stop 240/230 volts being routed into your phone( which would probably charge it very quickly but then it would blow up!) Also a resistor is the opposite of a conductor i.e something that resists conducting electricity.


What happen when ac current passes through resistor?

it resists the flow of cuurent


Inductor and capacitor?

An inductor is a magnetic device that resists a change in current. It is constructed with windings that can be backed by ferro-magnetic cores. The equation of an inductor is ... di/dt = V/L ... meaning that the rate of change of current per time is proportional to voltage and inversely proportional to inductance. Inductors, since they work on magnetic fields, can be coupled, as transformers, motors, and generators. A capacitor is a charge device that resists a change in voltage. It is constructed with parallel plates. The equation of a capacitor is ... dv/dt = I/C ... meaning that the rate of change of voltage per time is proportional to current and inversely proportional to capacitance. Inductors and capacitors, since they work in opposite phasor angles, can be coupled to make resonant filters, giving bandpass or bandcut to particular frequencies.


Why are resistors called resistors?

Resistors have resisting power(resists the electric power).Due to having the resistive property, the name resistor is given to such electrical device.

What is resistor in physics?

A resistor is a component of an electrical circuit that resists the flow of electrical current. A resistor has two terminals across which electricity must pass, and is designed to drop the voltage of the current as it flows from one terminal to the next. A resistor is primarily used to create and maintain a known safe current within an electrical component.


What is an object in an electric circuit that resists the flow of electrons?

A special kind of resistor can oppose the flow of an electrical current.


What is the definition of impedance in physics and how does it relate to the flow of current in an electrical circuit?

Impedance in physics refers to the measure of opposition to the flow of alternating current in an electrical circuit. It includes both resistance and reactance. In simple terms, impedance determines how much a circuit resists the flow of current, affecting the overall behavior of the circuit.


What the difference between Transistor and resistor?

A transistor is a semiconductor device used to amplify or switch electronic signals, while a resistor is an electrical component that resists the flow of current in a circuit, thereby controlling the amount of current. Transistors are active components that can amplify signals, while resistors are passive components that mainly control the current and voltage levels in a circuit.


Does resistance flow through a circuit?

No. Resistance does not flow. Resistance is the characteristic of a material that resists the movement of electrons and thus the flow of electrical current.


What is the symbol for inductor?

L is the symbol for inductance. An inductor is a passive two-terminal electrical component which resists changes in electric current passing through it.


What is the device that resists the flow of electrical current?

What does a car's blower motor resistor do?

Its an electric component that resists the flow of electrical current. Resistors are used to control the flow of current to the blower motor so that different speeds can be achieved


Capacitance is the property of an electrical circuit that?

A capacitor resists a change in voltage, proportional to current, and inversely proportional to capacitance. The equation of a capacitor is dv/dt = i/c.


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 are the differences between resistive load and inductive load in terms of their impact on an electrical circuit?

A resistive load directly resists the flow of current in an electrical circuit, causing a voltage drop. An inductive load, on the other hand, creates a magnetic field that can store energy and cause a delay in current flow. This can lead to power factor issues and voltage spikes in the circuit.


What does a filament lamp do in a circuit?

A filament lamp produces light by converting electrical energy into heat and then light. It acts as a resistive load in the circuit, meaning it resists the flow of current and causes the filament to glow and produce light.
