Electrical impedance is the measure of opposition produced by circuit elements in the path of alternating current. Therefore, the electrical impedance is the parameter related to the AC circuit. The electrical impedance is usually denoted by the symbol ‘Z’ and is measured in ohms $\mathrm{(\Omega)}$. The electrical impedance is a complex quantity, i.e. it has both magnitude and phase. The electrical impedance is basically the extended concept of resistance. It is the function of frequency of alternating current flowing in the circuit. It because the impedance comes into picture only when there is a frequency dependent element like inductor or ... Read More
In this tutorial, we will learn how to check if given two strings are anagrams of each other or not using Go programming language. A word or phrase formed by rearranging the letters of a different word or phrase by using all the letters exactly once is known as an anagram. Example − Roles anagram word is loser Binary anagram word is brainy The below example shows how to create an empty map using the built-in make () function. The make function allocates and initializes a hash map data structure and returns a map value that points to it. The specifics ... Read More
In this tutorial, we will learn how to check if a given string is numeric or not using Go programming language. We will be using the regexp package in Go to validate the numeric patterning of the string. Examples of numeric string − A string which has a numeric value in it T20CRICKET GOOD1 100PERCENT Syntax func MustCompile(str string) *Regexp //This function creates the regular expression func MatchString(pattern string, s string) (matched bool, err error) // This function returns a Boolean value that indicates whether a pattern is matched by the string Example 1: Golang Program Code ...

In this tutorial, we will learn how to check for Armstrong number in Go programming language. An Armstrong number or the narcissist number is a number whose sum of digits raised to the power three equals the number itself. Example1: $\mathrm{(1^3) \:+ \:(5^3) \:+ \:(3^3)\:= \:153}$ Example2: $\mathrm{(3^3) \:+ \:(7^3) \:+ \:(1^3)\:= \:371}$ In the below examples, we will read an integer number and then check the given number is an Armstrong number using Golang program Syntax Syntax of For loop Initialize for condition { } incrementor The initialization statement is optional and executes before for ...

In this tutorial, we will learn how to calculate the power using recursion technique in Go programming language. Power can be defined as a number being multiplied by itself a specific number of times. Exponent can be defined to the number of times a number is used in a multiplication. Powers and exponents are important tools to rewrite long multiplication problems in mathematics, especially in algebra. Example: 24 = 2 × 2 × 2 × 2 = 16, where 2 is the base and 4 is the exponent. A Recursion is where a function calls itself by direct or indirect ... Read More
In this tutorial we will write a Go-lang code to print a right Triangle star pattern. We will depict how you can print the star pattern in go language. * * * * * * * * * * How to print a star pattern? A right triangle star pattern is shown above, and in that pattern, you can see that stars are increasing with the increase in the number of rows. The pattern goes like this 1 star in first row, 2 stars in second row, and goes on. For loop for [condition | ( init; condition; increment) ... Read More
In this tutorial we will write a Go-lang code to print a Left Triangle star pattern. We will depict how you can print the star pattern in go language. * * * * * * * * * * How to print a star pattern?

In this tutorial, we will learn how to print half diamond star pattern using Go programming language. Syntax for initialization; condition; update { statement(s) } To use a for loop in go lang we first need to initialize a variable then specify the condition of the loop i.e when should the loop end then we need to increment or decrement the variable followed by the lines of codes that should get executed. Example 1: Golang Program Code to print Half Diamond Star Pattern Using a Single Function Approach The goal is to divide the pattern into ... Read More
In this article we will discuss about how to get real part from a complex number in Go language. A complex number in mathematics is a number that can be expressed in the form of a + ib where i is called iota. The value of iota is $\mathrm{\sqrt{-1}}$ and a and b are real numbers. The first part i.e ‘a’ is called real part of complex number and the part after iota i.e ’b’ is called imaginary part of complex number. Syntax func real(number complex128) float64 The real() function is used to get the get the real part ... Read More
In this tutorial, let us discuss the basic rules for JavaScript parameters. A JavaScript function is a code that performs a particular task. The function parameters are the name list in the function definition. Parameters are also known as formal parameters or formal arguments. We can follow the syntax below to declare parameters. Syntax function functionName(param1, param2) { } When there is no value for a parameter, a default value comes in place. Rules Declare the default parameters as the final ones to avoid an error. The JavaScript function definition does not specify a parameter type. The JavaScript ... Read More
