Question

help me I can't find this

Answer 1

i) there are 4 resistence of each 4 ohms

2 in series and other 2 in parallel
we need to find total res.

so firstly .. we add series resistence
4ohms + 4 ohms = 8 ohms (1)


now other 2 are in parallel
so we add by
1/R = 1/R1 + 1/R2
= 1/4 + 1/4
= 2/4
1/R = 1/2
R = 2 ohms........(2)


Now, we have 2 total resistance , which series is 8 ohms and parallel os 2 ohms
by adding both 8+2 = 10ohms




ii)
