Concept:

Source transformation:

In the source transformation of a circuit, a voltage source can be transformed into the current source, and a current source can also be transformed into the voltage source.

According to source transformation technique, a voltage source-series resistance combination is equivalent to a current source-parallel resistance combination if and only if their

  • Respective open-circuit voltages are equal
  • Respective short-circuit currents are equal
  • Resistance remains the same in both cases

 

1) Voltage source to current source

V = IR = 2 × 5 Ω  = 10 V

and series resistance R = 5 Ω

In a certain number system there are only two notations to represent numbers: @ and %. 0 is represented by @ and 1 by %. The subsequent numbers are represented in the following manner: 2 is represented as %@, 3 is represented as %%, 4 is represented as %@@, 5 is represented as %@% and so on. Based on this coded language, answer the following questions: What number is represented by %%@%@%%?
A word is represented by only set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are number alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix-II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example ‘A’ can be represented by 10, 75 etc and ‘B’ can be represented by 44, 79 etc. Similarly, you have to identify the set for the word ‘FOLDER’.  Matrix I    Matrix II   0 1 2 3 4   5 6 7 8 9 0 H L F M I 5 E I C J G 1 A U W S E 6 P R U S K 2 R Y C Z O 7 A W O D B 3 K T X V J 8 O T V Q L 4 D Q G P B 9 H N D M F
