A resistor has a fixed resistance which does not change. A variable resistor is a single unit in the circuit where the resistance can be altered....Become a member and unlock all Study Answers Start today. Try i
The resistance value is specified in ohms, the standard symbol is “R” orΩ. Resistor values are often stated as “k” (kilo, or times 1,000) or “M“, (meg, or times 1,000,000) for convenience. There are a few conventions that are followed, and these can cause problems for t...
Capacitors consist of two conducting surfaces separated by an insulator; a wire lead is connected to each surface.What is Capacitor and How Capacitors WorkCapacitor Symbol and UnitThere are two capacitor symbols generally used in electronics. One symbol is for polarized capacitors, and the other is...
Because of their design, they can only be used once, but they can be used in applications where they may need to be replaced because they are intended to fail. The fusible resistor symbol is shown below. This is the combination of a resistor and a fuse. Fusible Resistor Symbol Fusible Re...
Capacitors are devices which store electrical energy in the form of an electric field. The process is quite similar to the way mechanical springs store energy in the form of elastic material deformation, to the extent that the math describing both is quite similar, save for the variables used....
What is the unit and formula of capacitance?Answer and Explanation: The unit for capicitance is farad with the symbol F. It is named after Michael Faraday, an English physicist, who has discovered the capacitor. To be able to compute for the capacitance of a capacitor, these formula is ...
A rheostat definition is, it is one kind ofvariable resistorwhich is mainly used for controlling current as well as to changethe resistancewithin a circuit without disruption. The name of this component was taken from two Greek words namely ““rheos— & ““statis—...
The new overall resistance of the bottom resistor in the voltage divider is R2 in parallel with R3. If we call this resistor Rt, then this is easy to calculate from the fact that it is two resistors in parallel.It is easy to calculate the new value for Rt using the formula for two ...
What is the reactance of a5.40μFcapacitor at the frequencyf = 1.30 Hz? Capacitive Reactance: XC (Ω) Answer and Explanation:1 Given data: The capacitance isC=5.40×10−6C The frequency isf=1.30Hz The expression for... Learn more about this topic: ...
The two terminals are named asAnodeandCathode, we will get into the symbol and how to identify the terminals later, but for now just remember that any diode will have only two terminals (at least most of them) and they are Anode and Cathode. Another golden rule with diodes is that they...
