In the following figure, the equivalent resistance between ‘A’ and ‘B’ will be
equivalent resistance between ‘A’ and ‘B’
Two resistances combine in series order to provide 50 ohms resultant resistance, and when they combine in parallel order, they provide 8 ohms resultant resistance. Then the value of each resistance is:
