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..
