- How is thevenin equivalent calculated for this network
The attached image (Horowitz & Hill Student Manual for 2nd ed) gives thevenin resistance and voltage for the network R_1+(R_2||R_L) as
R_th=R_1||R_2
E_th=E_in(R1/(R_1+R_2)) E_th is self-evident (voltage divider) but how in the world they get R_th i beyond me. If there is no load, isn't R_1 in series with R_2 no matter what?
Many thanks in advance
