In the circuit shown in Figure 19.61 current flows through the 5.00$\Omega$ resistor in the direction shown, and this resistor is measured to be consuming energy at a rate of 20.0 $\mathrm{W}$ . The batteries have negligibly small internal resistance. What current does the ammeter $A$ read?
the current passing through the ammeter is 0.714 $\mathrm{A}$

it is given in the problem That power dissipated by a five. Mr is 20. What? So we hell well are dissipated by five? Home Mr is equal to 20. Work s. We have power equal to secure off current times Really sense so we can ride this airs But untrue. Five home minister times reticence. He really senses 5.0 home. Equal to going to what? So from here the hell current room five mom resistance is he called Tau for is equal to two and you're no Well, it does. No, this point after circuit is a on them. This one is B This one s c This honesty then this one is S e on this one s if nobody using the good jobs Second rule for the close Loof me e d. C. Then back to be And let us assume that kern flow into room seven homeless stories. I no from be true e The potential drop is Is the current isn't minus. Garden is doing here. Times are your senses. Five home on from D to C the negative side up. The biggie comes first. So we are going from low potential Alberti toe Hypertension Liberty. That's why potential change, Abertis Positive So bless 15 world minus potential. Drop in the wrister off seven. Home is minus items. Seven Oh, Physical toe zero on recon. Right. He says, minus through fire. Sit in den world. Unless for Dean World minus I And 27 they go to zero Our recon, right? It is minus I time 70 is equal. Do minus firewalled. Our recon ratchet. Yes, I equal to minus firewalled upon minus seven. Oh, So we have occurred equal to 0.7 one for MPs. This *** buzzing through seven. Home minister asked a meter emitter. Betty, between world of beauty and mystery are in serious condition. So the current flowing through every terror will ask me the same So the middle will read seven point. Sorry. The middle really read 0.714 And dear God
