Unformatted text preview: 7.5 7.5 Ω a b V 7.5 Ω 1A a b I N = 7.5 V / 7.5 Ω = 1 A Converting Thevenin's Into Norton's R N = 7.5 Ω R N = R Th I N = V Th / R Th Best to simply determine Thevenins and then convert to Norton. Examples TT2 1. What resistor draws a current of 5 A when connected across terminals a and b of the circuit shown below? 100 V 5 20 6 5A Ω Ω Ω R = ? a b Solution: Find the Thevenin equivalent circuit. V Th = V ab (when open) = ( 29 ( 29 20 5 20 100 + V = 80 V R Th = 6 + 5  20 = 6 + 1/ (1/ 5 +1 / 20) = 10 Ω V / R t = 5 A ⇒ R t = 80 V/5 A = 16 Ω so R = 16  10 = 6 Ω R 80 V 5A 10 Ω Thevenin Equivalent 2. Find the Thevenin equivalent circuit at terminals a & b of the circuit below: TT3 Solution: 3. Find the Thevenin equivalent circuit at terminals a & b for the circuit below: TT4...
