5. Draw the complex circuit described below:
A 12 volt emf source connected in series with R1 (3 ); in series R1 there are
R2 (2) and lamp 1 (4) which are in parallel with each other. Connected in series to
that parallel loop is another parallel loop, which includes on one branch, R3 (5),
R4 (2), and Lamp 2 (3) in series, and on the other branch of this parallel loop is
R5 (7). After that parallel branch there is a 20  resistor (R6) which is in series with
all other components.
