What is an Electrical Resistor? A resistor (also known as an electrical resistor) is defined as a two-terminalpassive electrical elementthat provideselectrical resistanceto current flow. Resistance is a measure of the opposition to the flow of current in a resistor. The larger a resistor’s resi...
A. To increase the voltage. B. To decrease the current. C. To increase the current. D. To change the direction of the current. 相关知识点: 试题来源: 解析 B。解析:在简单电路中,电阻器的作用是减小电流。电阻器不能增加电压,也不能增加电流,更不能改变电流方向。反馈...
A Resistor is an electrical device that resists the flow ofelectrical current. It is a passive device used to control, or impede the flow of, electric current in an electric circuit by providing resistance, thereby developing a drop in voltage across the device. We need some way to control...
What Is a Resistor? The majority of electric circuits commonly contain a resistor. An electrical resistor is indeed a passive part that prevents or hinders the passage of charges. Resistance is the ability of a resistor to restrict the flow of electricity through a circuit or a component. Each...
Theelectrical resistanceof an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. A conductor has free electrons randomly moving inside. When anelectric potential is applied to it, the electrons collide with other atoms and molecules of the conducto...
A resistor is an electrical component with two terminals that is used to limit or regulate the flow of electrical current in electronic circuits. Its purpose is to reduce current flow as well as lower the voltage levels in its general vicinity or portion of the circuit. A resistor is meant ...
The tap in the analogy of the water system corresponds to changing he resistance of the resistor. When the tap is off, then this is equivalent to a switch stopping any current flow into e electrical circuit.Relationship between resistance, voltage and current...
