Answer:Part A)Since all of the resistors have equal resistance, hence for finding even only 1 branch It will be fine because current will be the same for all branches.

=>

=>

=>

I = 2 APart B)Equivalent resistance for parallel circuits is the sum of reciprocals of each resistor.

=>

=>

=>

=> R = 15/3

=>

R = 5 ohmsPart C)I = V/R

Where I is current, V is voltage and R is the equivalent resistance

=> I = 30/5

=>

I = 6 A
