What is Trial Balance? Meaning, Definition, Format & Objectives

Trial balance is a statement which takes into account all the debit and credit balances from the ledger accounts. It is prepared in order to verify whether the balance of debit side is same as that of the credit side. Trial balance can also be defined as a statement consisting of balances of different ledger accounts on a specific date. When both the sides of trial balance tally it means that books of accounts are accurate.

Octal to Binary Converter – Steps, Table & Examples

Octal to Binary Converter
Binary equivalent:
Octal to Binary Converter

Thus, an Octal to Binary Converter is a tool that is used to convert a number represented in octal (base-8) notation to its binary (base-2) equivalent. The tool takes an octal number as input and performs the conversion using a simple process that involves replacing each octal digit with its binary equivalent. This process results in a binary number that is equivalent to the original octal number.

Octal numbers are often used in computer programming to represent sets of three bits at a time, while binary numbers are used to represent individual bits. So, it’s useful to be able to convert between these two numbering systems when working with computer programming. An octal to binary converter can help you quickly and easily convert octal numbers to their binary equivalent, saving you time and effort in your programming work.

Steps to convert Octal to Binary

Converting an octal number to a binary number involves a simple step-by-step process. Here are the steps:

  • Write down the octal number.
  • Convert each octal digit to a 3-bit binary number. You can do this by replacing each octal digit with its binary equivalent using the table below:

Table 1: Octal to Binary Conversion table

4

100

5

101

6

110

7

111

  • Write the binary equivalents of each octal digit next to each other in order from left to right to form the binary equivalent of the octal number.

Let’s go through an example to illustrate these steps. We will convert the octal number 752 to binary.

  • Write down the octal number: 752.
  • Convert each octal digit to a 3-bit binary number using the table 1. The octal digit 7 has a binary equivalent of 111. The octal digit 5 has a binary equivalent of 101. The octal digit 2 has a binary equivalent of 010.
  • Write the binary equivalents of each octal digit next to each other in order from left to right to form the binary equivalent of the octal number. So, the binary equivalent of the octal number 752 is 111101010.

Solved Examples to convert Octal to Binary

Here are some examples of converting octal numbers to binary:

Example 1: Convert the octal number 73 to binary.

  • The given octal number is 73.
  • The octal digit 7 has a binary equivalent of 111.
  • The octal digit 3 has a binary equivalent of 011.
  • So, the binary equivalent of the octal number 73 is 111011.

Example 2: Convert the octal number 456 to binary.

  • The given octal number is 456.
  • The octal digit 4 has a binary equivalent of 100.
  • The octal digit 5 has a binary equivalent of 101.
  • The octal digit 6 has a binary equivalent of 110.
  • So, the binary equivalent of the octal number 456 is 100101110.

Example 3: Convert the octal number 17 to binary.

  • The given octal number is 17.
  • The octal digit 1 has a binary equivalent of 001.
  • The octal digit 7 has a binary equivalent of 111.
  • So, the binary equivalent of the octal number 17 is 001111.

What is an Ideal Transformer? Working, Phasor Diagram, Formula & Properties

An ideal transformer is the transformer having the following Properties.

  1. The losses are zero (No iron loss, no copper loss).
  2. The primary and secondary winding resistances are zero.
  3. The leakage flux is zero. Therefore all the flux produced by the primary winding is coupled to the secondary.
  4. A small current is required to develop flux inside the core. This happens because the permeability of the core is very large.
  5. The external voltage applied to the primary, V1 is same as the primary induced voltage El. This is because the primary winding resistance is zero and so there is no voltage drop across it.

\[{{E}_{1}}={{V}_{1}}\]

  1. Similarly the voltage induced in the secondary winding (E2) will be equal to the load voltage V2, because the secondary resistance is zero.

\[{{E}_{2}}={{V}_{2}}\]

8. The transformation ratio for an ideal transformer is given by

\[k=\frac{{{E}_{2}}}{{{E}_{1}}}=\frac{{{V}_{2}}}{{{V}_{1}}}\]

  1. Efficiency of an ideal transformer is 100%. This is because there are no losses taking place.
  2. The voltage regulation is That means the secondary voltage will remain constant irrespective of the load current.
