Eyeballed the top part of the top circuit:
It's clearly about 3 in parallel with about 6 in series with 7, that's
roughly a bit less than 10 ohms?
That 'a bit less than 10' is again in parallel with about 7.5 ohms.
So 10 x 7.5 all divided by 17.5 = about 4.3 ohms.
And if the applied DC voltage is 12 then current will be 'about'
`12/4.3 or about 2.8 amps, or a little higher.
Wattage, either way (I^2 x R or V x I) is about 34 watts.

Still working on bottom one.

Back later, it's supper and TV news time..

Oh by the way my assumption is that ALL the lights in top diagram are
incandescent? True?

Are all the 'lights' in bottom diagram LEDs?????????????????????
