I chose the second loop. The one that had two 5 V batteries and a 10 ohm resistor

#

I got 0 amps

#

Which is not the right answer

#

Kirchoffs voltage law for the second loop came out to be

5V-(10 ohm*I)-5V=0

#

0 = (10 ohm * I)

#

I= 0 amps

#

Wrong answer

why -5?

#

notice the direction

#

its +5

#

frosty nexus why -5?

Well the batteries are connected in series but like in opposite directions no?

#

Ok wait

#

I got it

#

betterSkull

#

LMAOOOOO

#

You’re right

#

They are boosting the emf in this case

#

yeah in both cases you go from - to +

#

or + to -

#

frosty nexus yeah in both cases you go from - to +

Yeah sorry I messed up

#

Thanks for pointing it out

#

:p

depending on direction of loop
