Unformatted text preview: 2 1 1 1 1 1 R R R R i i eq When there are only resistors, then 2 1 2 1 2 1 1 1 1 R R R R R R R eq ⋅ + = + = and, 2 1 2 1 R R R R R eq + ⋅ == (5) Why R eq for series R, and G eq for parallel R? Simplicity!! ↑ i in A ↓ i 1 G 1 B Geq ↓ i 2 ↓ i 3 G 2 G 3 ⇔ ↑ A B + – + – i in v in Geq 4 4. Current Division i 1 i in = ? i 2 i in = ? i 3 i in = ? General Form Current distributes across a parallel resister circuit in proportion to each branch G. ) ... , 3 , 2 , 1 ( n i G G i i i i i in i = = ∑ ↑ i in ↓ i 1 G 1 ↓ i 2 ↓ i 3 G 2 G 3 + – v in 5 Practice Problem 1 . (1) Find R eq and G eq (2) Find V in 6 (3) Find V x (Hint: Use Voltage Division) (4) Find I y = I 6 Ω (Hint: Find I 3 first, then use Current Division) 7 Practice Problem 2 . Find R eq .
