Credit Policy: DefinitionCredit policy is mainly dependent on the volume of credit sales and the collection period. The volume of credit policy is a function of a company’s gross sales and the percentage of credit sales to total sales. Total sales of a company depend on many factors, such as market size, market share, quality of products, competition, etc.Companies may sell their products in credit for various reasons, such as gaining more market share and being competitive in the industry. Credit sales create trade debtors or accounts receivables where the seller needs to wait for a certain period for the ... Read More
Converter and inverter are both two important power-electronic devices in the field of electrical and electronics engineering. Inverters and converters are used for the conversion of AC power into DC power and vice-versa which is a very important phenomenon in the field power electronic engineering as well as in our day-to-day life.The most significant difference between these two devices is that a converter is a power-electronic device which can transform the electric power from one form (AC or DC) to another form (AC or DC), while an inverter is a type of power electronic converter which converters DC power into ...

The electronic circuit which is used to convert alternating current (AC) into direct current (DC) is known as a rectifier. The process of converting the alternating current into direct current is called rectification. The main component of the rectifier which performs the rectification is the semiconductor diode.Depending upon the type of conversion from AC to DC, i.e. half cycle of AC or full cycle of AC, rectifiers can be grouped into two categories −Half-wave rectifierFull-wave rectifierBased on the circuit configuration, the full-wave rectifier is further classified into two types viz. −Centre-tapped full-wave rectifierBridge rectifierThus, both centre-tapped and bridge rectifiers are ...

In an electric circuit, the rate at which the work is being done (or the energy is being expended) is known as electric power. Mathematically, electric power can be defined as the work done (or energy expended) per unit time, i.e., $$\mathrm{Power, \mathit{P}\:=\:\frac{Work\:done\:(\mathit{W})}{Time(\mathit{t})}}$$The unit of electric power is Joules per second.Based on the type of current, the electric power can be of two types viz.: DC power and AC power. The AC power is further classified into three main types as −Apparent power (S)Active power (P)Reactive power (Q)In this article, we will discuss about what the apparent power and the ... Read More
Ammeter and galvanometer are both measuring instruments used to measure the current flowing through a circuit. The most significant difference between a galvanometer and an ammeter is that the ammeter measures only the magnitude of the current flowing in the circuit, while the galvanometer shows both magnitude and direction of the current in the circuit.Go through this article to know more about ammeter and galvanometer and the key differences between these two measuring instruments.What is a Galvanometer?A galvanometer is an electromechanical measuring device used to measure the strength of current and direction in an electric circuit. A typical galvanometer consists ... Read More
In JavaScript, We can use the reduce() method to apply a function against an accumulator and each key of an object (from left to right).The reduce() method is called on a given array and takes in a callback function as its first argument. Please refer to Array reduce() for more details. Let’s look at the syntax of this method.Syntaxarray array.reduce(callback[, initialValue]);Parameterscallback − Function to execute on each value in the array.initialValue − Object to use as the first argument to the first call of the callback.The callback function is passed with four argumentsThe first argument is the accumulator, which is ...

In this tutorial, we'll be discussing how to get the sum of the powers of all the numbers from start to end in JavaScript. We'll be using the built-in Math.pow() method to calculate the powers and the Array reduce() method to sum up the values.Using the Math.pow() methodThe Math.pow() method allows us to calculate the power of a number. We can use this method to calculate the powers of all the numbers from start to end.SyntaxMath.pow(base, exponent) ;ParametersBase − The base number.Exponents − The exponent to which to raise the base.ExampleFor example, if we want to get the sum of ...

What is Cache?A cache is a data storage mechanism that allows users to retrieve data or files on computers quickly.Caches can be found in both hardware and software. Caching reduces data access latency by acting as an intermediary between the primary storage appliance and the receiver hardware or software device.A cache provides similar capabilities in both hardware and software. It's a type of internal memory with a tiny form factor that saves instances of the most frequently executed programs in main memory for faster access when the CPU needs them in physical or hardware form.We are all familiar with the ...

We could apply String split(), Array sort() and Array join() methods to write a function that returns a passed string with letters in alphabetical order in JavaScript. A JavaScript function is a block of code that is executed when it is invoked. A string is a sequence of characters. In JavaScript, strings are represented by the type String.Input string : tutorialspoint Output string: aiilnooprstttuStepsSplit the string into an array of characters using split() method.Apply the sort() method to sort the characters in alphabetical order.Finally, we use the join() method to join the characters back into a string.The Array.sort() method sorts the ...

JavaScript provides two functions for dealing with encoded strings: escape() and unescape(). The escape() function is used to encode a string, making it safe for use in a URL. The unescape() function is used to decode an encoded string.The differencesThe main difference between the two functions is that escape() encodes characters that are not ASCII, while unescape() only decodes those characters. This means that if you use escape() on a string that only contains ASCII characters, the result will be the same as the input string. However, if you use unescape() on a string that contains non-ASCII characters, the result ... Read More
