Question

(A) Compute the load current you would expect to measure if the load resistor in Figure 12-2 was replaced with a short circuit?

(B) Repeat the computation for the Thevenin Circuit drawn above.

V(th)=7.157V , R(th)=753.3ohms, potentiometer = 1kilo ohm

Explanation / Answer

A)

equvivalent resistance R=270+(560||680)=577.097 ohms

Current I=V/R=10/R=17.33 mA

current in the load branch =I*680/(680+560)=9.5 mA

B)

Vth=10-i(Rth+r)=7.157V

10-1753.3*i=7.157

i=1.62 mA
