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...
Ohm's law says that in an electrical circuit, the current passing through a resistor between two points, is related to the voltage difference between the two points, and inversely related to the electrical resistance between the two points. This relation is shown in the following pee Where I ...
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...
Chapter 1 - Resistor Fundamentals The resistor is a passive electrical component that creates resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms (Ω). An ohm is the resistance that occurs whe...
1RT=1R1+1R2+1R3+...+1Rn , where R1,R2,R3 are the resistances of the resistors and Rn is the resistance of the nth resistor. Answer and Explanation: We are given that: R1=7Ω R2=10Ω R3=6Ω R4=4Ω In this question, we need to....
What is the value of the current through a 12-ohms resistor? In the figure E = 6.02 V, R1 = 124 ohms, R2 = 329 ohms, and R3 = 604 ohms. What are (a) the equivalent resistance of the three resistors? (b) the electric potential ...
A shunt resistor (or shunt) is defined as a device that creates a low resistance path to force most of theelectric currentthrough the circuit to flow through this path. In most cases, a shunt resistor is made up of a material having a low-temperature coefficient of resistance, giving it ...
A 12V AC to DC converter for LED lights is an essential electronic device that transforms the AC voltage into a DC voltage suitable for powering LED lights. When choosing a converter, it is important to consider factors such as voltage output, current output, wattage, efficiency, and reliabilit...
A material that conducts electricity fairly well but not as well as a conductor is known as aresistor. The most common example of a resistor is a combination of carbon and clay, mixed in a specific ratio to produce a constant, predictable opposition to electric current. ...
