PART A)
Equivalent resistance in parallel is given as
now we have
PART B)
since potential difference across all resistance will remain same as all are in parallel
so here we can use ohm's law
As we know i = 7 A current flows through 15 ohm resistance
PART C)
Similarly ohm's law for 20 ohm resistance we can say
Answer:
11.6 s
