Question
VTh = ______________________
RTh = ______________________
What load resistor must be attached across the output terminalsfor maximum power transfer?
RL = ______________________
Find the current through, voltage across and power disipated bythe load resistor.
IL = _______________________
VL = _______________________
PL = ______________________
Explanation / Answer
finding vt: since vt is open the 1kohm resistor is short. next, we labelnodes: top mid node: vt top left node: 12 kcl at vt: (vt - 12)/330 + vt/210 = 0 vt = 4.67v finding rt and rl: rt = rl first we short voltage source and find req: rt = (330||210) + 1000 rt = rl = 1128.23 ohms finding il: il = vt(rt+rl) il = 4.67/(2256.46) .002A finding vl: we just use ohms law: vl = (rl)(il) vl = 1128.23 * .002 vl = 2.256v finding pl: pl = (vl^2)rl pl = .005 THANK YOU AND PLEASE RATE
