48. petrucci

:)

49. rocky987

are vOUT and Vout same denote same OUTPUT VOLTAGE

50. 1431mahi

aybody formulae plzzz

51. rocky987

plzz somebody help me with q6 plzzz

52. nirvanaguy

The circuit elements have the following values: Vin=18V, R1=1.5Ω, R2=3Ω, R3=4Ω, A=1.5 and B=0.5. 1)1.8 2)1.8 3) 1.8 4) i'm still working on that

53. nirvanaguy

if you have the above numbers my answer is correct. please select best response if you have those #s

@nirvanaguy pls post if u get the last answer :)

55. Neelima

@nirvanaguy plz post the formulae........

Vo* (R3-(B*R1*R3)+R1+R2+A*R2)/(R3-B*R1*R3)=VIN i1=V0/(R3-B*R1*R3) vo and vth are same

gotto find Rth

how

59. jayapavan

for Vin=42V, R1=4Ω, R2=4Ω, R3=7Ω, A=1.5 and B=0.125. i1=2.4 vout=8.4

60. jayapavan

for The circuit elements have the following values: Vin=15V, R1=0.5Ω, R2=1.5Ω, R3=5Ω, A=2 and B=1.5. i=2.3 vout=3

61. nirvanaguy

FOR ANYONE WITH THESE NUMBERS ON #6 The circuit elements have the following values: Vin=18V, R1=1.5Ω, R2=3Ω, R3=4Ω, A=1.5 and B=0.5. 1)1.8 2)1.8 3) 1.8 4) 3.6V i1 = 2 A, and the current source is taking .75 i1 which means that the short circuit current is .25i1 = .5 A. If Vth= 1.8 and Isc=.5 A, Rth = 3.6 Ohms

62. rocky987

whatz d formula for Rth?

63. nirvanaguy

Vth/Isc.. duh

what is isc

@nirvanaguy

66. nirvanaguy

Isc is the short circuit current.. in this case .5A if you have those #s. If not then redraw a short circuit in place of the R3 and solve for i1. once you solve for i1, see how much the current source is draining and the remaining is sent through the short circuit

67. machu

Thanks @jayapavan Hv u found rth for values: Vin=15V, R1=0.5Ω, R2=1.5Ω, R3=5Ω, A=2 and B=1.5......@chanakya2346 hav u?

68. chanakya2346

no @machu

69. chanakya2346

@machu The circuit elements have the following values: Vin=42V, R1=4Ω, R2=4Ω, R3=7Ω, A=1.5 and B=0.125.

70. machu

sorry i typed it wrong..mine is same as urs Vin=42V, R1=4Ω, R2=4Ω, R3=7Ω, A=1.5 and B=0.125.........

71. machu

@chanakya2346

72. chanakya2346

have u got the ans @machu

qThe circuit elements have the following values: Vin=27V, R1=5Ω, R2=7Ω, R3=12Ω, A=6 and B=0.1.

plz give rth

75. machu

Just waiting for lucky star @chanakya2346 , jayapavan may hv the ans

76. engr.usman

The circuit elements have the following values: Vin=42V, R1=4Ω, R2=4Ω, R3=7Ω, A=1.5 and B=0.125. kindly tell me the i1, vout, vth and rth

77. machu

scroll up buddy @engr.usman

78. aakash.kasina

@nirvanaguy did u get Vth

79. jayapavan

no even im trying to find vth and rth

80. machu

vth is same as vout..i checked

81. machu

@chanakya2346 ,did u get it all right ..except rth?

82. chanakya2346

i havent checked becoz i have only submission left @machu

83. rocky987

84. rocky987

Vin=45V, R1=1.5Ω, R2=2Ω, R3=6Ω, A=2 and B=0.5.

85. rocky987

86. rocky987

any one with q6 with parameters Vin=45V, R1=1.5Ω, R2=2Ω, R3=6Ω, A=2 and B=0.5 please tell the value or the formula for rth...please please

87. graydarl

(q6) The circuit elements have the following values: Vin=27V, R1=5Ω, R2=7Ω, R3=12Ω, A=6 and B=0.1. please help

88. graydarl

we need a genius everyone that finds a genius must bring him here

89. EliteTUM

Vin=42V, R1=4Ω, R2=4Ω, R3=7Ω, A=1.5 and B=0.125 i1 = 2.5 vOUT = 8.4 vTH = 8.4 RTH = 5.6
