Q$6$: A$-$ Explain the function of the below component used as a part from power system.

B$-$ Four equal resistors $($R$1,$ R$2,$ R$3,$ and R$4)$ are connected as shown below, each resistor includes $100$ equal wire$-$wound resistors each each one equals to $1$ MO $,$ all are serially connected, they form a hellix of $20$ windings. Calculate:

$1-$ Total current passing through the total mixed connection resistors.

$2.$ Power dissipation at each winding resistors and at each resistor if the input dc supply voltage equals to $200$ kV which has dropped between A and $8.$
