$($a$)$ Find the Th$$venin equivalent resistance of the circuit to the left of the

dashed line shown in Figure $6.$

$($b$)$ Find the Th$$venin equivalent voltage of the circuit to the left of the dashed

line shown in Figure $6.$

$($c$)$ Draw the Th$$venin equivalent circuit of the circuit to the left of the dashed

line shown in Figure $6.$

$($d$)$ Hence or otherwise, determine the voltage VL across the load circuit to the

right of the dashed line, if it were now connected to the circuit to the left.
