In the circuit in Figure P3.21, assume the source voltage and source current and all resistances are known.

a.    Write the node equations required to determine the

Figure P3.22

3.23  In the circuit shown in Figure P3.23, VS2  and RS

model a temperature sensor, that is,

VS2  = kT                  k = 10 V/◦C

VS1  = 24 V            RS  R1  = 12 kQ

R2  = 3 kQ         R3  = 10 kQ

node voltages.

b.    Write the matrix solution for each node voltage in

R4  = 24 kQ      VR3

= −2.524 V

terms of the known parameters.

The voltage across R3, which is given, indicates the temperature. Determine the temperature. R1 Figure P3.21
