Hi everyone
I have to thevenise this circuit. I have done the problem but would like your input since I have not done this in a very long time.
Finding Rth
(1/20 + 1/8 ) ^-1 = 7.714ohm.
( 1/7.714 + 1/5 )^-1 = 3.03ohm
3.03 + 2 = 5ohm
soo Rth = 5ohm
Find Vth or voltage over 5ohm.
Rtotal = 20 + (1/8 + 1/(5+2))^-1 = 23.73ohm
Itotal = 20 / 23.73 = 0.85579 Amp.
V-20ohm = IR = 0.85579 * 20 = 17.115V
V-8ohm = 20-17.115 = 3.73V
So V-5ohm = 3.144( 5 / 2+5 ) = 2.2457V
Am I correct in assuming that the voltage over 5-ohm is what they are looking for in the question ?
Could this be a legitimate Rth and Vth answer?
Thanks
