Explanation / Answer

a) s2 is closed so this will form loop and

V= 2E

I= 2E/3R

b) let distribute the current as shown in figure

i0= i1 +i2

io= 2E/3R

i1= 0

i2 = current in 3R = 2E/3R

c) take the first bigger loop

and using kirchoffs volatage law

5E + 2IR + IR -E-2E =0

I (current in 2R) = 2E/3R

d) current = 0

e) potential difference between c and D = 3E ( none of above )

f) then also it will be 3E because curent will flow in resistors

g ) it will be 5E
