For the following circuits, use KVL and Ohm's Law to find the indicated voltage or current, and then calculate any other required quantities. Clearly identify what law you are using.
1. Find V, I + V2 = R12.
2. Find: V2, V3, and V3 = NOY82 + 7n.
3. Find: I PDEL, I4Y, POEL, AV, and WIWTIS6OINGDNIN.
4. Find: I = 4V and 4Y = 22.
