Question

1) Notice that there are two loops, labeled 1 and 2 in this circuit. Does it matter that there is no battery in loop 1, but only two resistors? Explain. O Yes. A battery is necessary to allow the current to flow O No. A loop can have any number of batteries, indluding none at all () The currents through the three resistors are labeled as OYes. If we choose the wrong direction, it will affect the magnitude of the currents O No. If we choose the wrong direction, it will only affect the sign of the answer l, and l Does it matter which dir rection, eft-to-right or rghe-to-eft, has ben chosen for each drcut we place and signs on the end of each resistor, does it matter which side is + and which is o Yes. Once we've made our choice for the direction of the currents, if we choose the o No. Once we've made our choice for the direction of the currents, we choose the wrong slacement of + and - it will only affect the sign of the answer wrong placement of + and-, it will affect the magnitude of the currents (iv) When we evaluate the potential drops and rises around a closed loop, does it matter which direction, deckwise or counterdlockwise, is chosen for the evaluation? Yes No Use Kirchhoff's junction and loop rules to determine the currents through the three resistors.(Due to the nature of this problem, do not use rounded intermedate values in your answers submitted in Webässign. Indicate the direction with the sign of your answer.) O Type here to

Explanation / Answer

1) No, a loop can have any number of batteries , including none at all

2) No, if we choose the wrong direction it will only affect the sign of the answer

3) yes, once we have made our choice for the direction of currents, if we choose the wrong placement of + or - it will effect the magnitudes of currents

4) No ( the direction is arbitrary)
