I'm not quite sure how it would be.. But if 60 W is dissipated from r1 then the current running through r2 should be 60w/r2= 60w/30ohm = I=2 ?

The amount of I running into the circuit is the same running out..But how am I going to find the find the current running into the circuit before the loops?

I've been trying articles all over the website but nothing will help me

Thank you:) I'm not sure how to do these, in Question 1 I thought about the thing that the resistors were parallel connected. Which should give a resistance on 10 ohm. BUt then I'm not sure what to do. In question 2 I've tried to use the law of Ohm, but without any succes In question 3 I...

Hi out there! I've been handled 3 questions which for me is rather hard and therefore I'm asking the experts. Any help would be great:) Donkey Kong Question 1) A circuit consists of a 15Ω and a 30Ω resistor connected in parallel across a battery of internal resistance 2 Ω. If 60W is...
