The current drawn when displaying the number8 will be? a. 60mA b. 80mA c. 50mA d-70mA 4. The decimal number 106 converted to a BCD code becomes? a. 0001 000 0110 d. 111000110011 5. The BCD code 1000 0010 0100 converted to a decimal number is? a. 724 b. 826 c. 824 d.623Explanation / Answer
1. option B a bcd to seven segment decoder has four input lines and seven ouput lines
2. option B in an encoded BCD to decimal Decoder , for a decade the decoder requires a single active devide
3. option D ther are seven sigments in display, if each sigment draws 10mA then the for displaying 8 all sigments has to enerzige so it draws 70mA
4.option A
5 option C
