In Exercises 65–68, find the first four nonzero terms of the Taylor series generated by ƒ at x=a.

PHYSICS 2401 WEEK 8 Chapter 28 DC Circuits Ideal Battery: Remember : Ph= I * R = V /R = V*I Model of non-ideal battery (real life) r = internal resistance ε= open current voltage Isc = ε /r comes from R = V/I V t I*R =L ε - I*r Battery Pb= P h 2* 2* ε*I = I r + I R * * ε = I r + I RL EX. A battery with ε = 10 V, internal resistance of 1Ώ, connected to R = 4Ώ. Find I. L Pb= P h 2* 2* ε*I = I r + I R I = ε/(r R L I = 10/(1+4) I=2 A EX. A battery connected to a R L,1= 10 Ώ, has V t 35V. When connected to a R L,2= 25Ώ, has V t 39V. Find ε,r. 1 = V/t L,1= 35V/10Ώ = 3.5A 2 = V/t L
