EGR203 Electric/Electronic Circuits Assignment 2

1. Convert the following numbers as specified:
   1. (1011011101)₂ to decimal and hexadecimal
   2. (EB7)₁₆ to decimal
   3. (124)₁₀ to binary and hexadecimal
   4. (A9B)₁₂ to decimal and hexadecimal
   5. (475)₈ to decimal and hexadecimal
   6. (827)₁₀ to duodecimal (base 12)

2. Convert the decimal number 751 to
   1. hexadecimal
   2. octal
   3. binary

3. In the duodecimal system, find
   1. the largest single-digit symbol (following the practice of hexadecimal A-F)
   2. the range of decimal numbers that can be represented by three duodecimal digits.
   3. the duodecimal number corresponding to 57₁₀

4. Find
   1. the range of unsigned decimal numbers that can be represented by 10 bits
   2. the range of signed decimal numbers that can be represented by 10 bits
   3. the range of hexadecimal digits that can be represented by 10 bits.
   4. why the number of bytes represented by a binary one following by 10 zeros is called a kilobyte.

5. For the following circuit, find (a) the value of the current I, (b) the value of the voltage across each resistor, and (c) the power absorbed or produced in each element.

   Vs	R1	R2
   6 Volts	140 Ω	160 Ω

   

6. Find the value of the current I flowing into the node.

   

7. Given the following circuit, find the resistance across the indicated points.

   R1	R2	R3	R4
   300 Ω	150 Ω	250 Ω	100 Ω
