(i) Find the value of current I in the circuit given as below:
(ii) You have four resistors of 8 $\Omega $ each. Show how would you connect these resistors to have effective resistance of 8 $\Omega $?
(i)(ii) Two 8 $\Omega $ resistors are connected in parallel. Two such parallel combination must be connected in series to get effective resistance of 8 $\Omega $.Such combination is shown as below:
