Question 4

A voltage of 24 V DC is applied through switch S to an R-L series circuit. Switch S was initially open. At time

switch is closed. The rate of change of current through the resistor is 8 A/s, while the current through the inductor is 8 A. If the value of inductor is 1 H, then for this condition the value of the resistor will be

Question 5

If the three resistors in a delta network are all equal in values i.e. R_DELTA, then the value of the resultant resistors in each branch of the equivalent star network i.e. R_STAR will be equal to:
(R_D→R_DELTA ; _Rs→R_STAR)
