REMARKS Substituting these values back into the original equations verifies that they are correct, with any small discrepancies due to rounding. The problem can also be solved by first combining resistors. QUESTION How would the answers change if the assumed directions of the currents used in solving the problem were all reversed in the figure above, but you followed the circuit paths in the same way to write down the equations based on Kirchhoff's rules? (Select all that apply.) The sign of each current-times-resistance term would reverse. The sign used for the voltage across the battery would reverse. The sign of the resistances would reverse. The signs of the currents after solving would reverse. PRACTICE IT Use the worked example above to help you solve this problem. Find the currents in the circuit as shown in the figure below by using Kirchhoff's rules. R = 5.4 0. A A A 4.00 A < > > EXERCISE HINTS: GETTING STARTED | I'M STUCK! Use the values from PRACTICE IT to help you work this exercise. Suppose the 6.0-V battery is replaced by a battery of unknown emf, and an ammeter measures I₁ = 1.8 A. Find the other two currents and the emf of the battery. 1₂ A V R ww 9.00 6.0 V
