Construct the network of Fig. 13.2. Insert the measured value of R in Fig. 13.2.

Question

Construct the network of Fig. 13.2. Insert the measured value of R in Fig. 13.2. Record the measured R_L value in the first column of Table 13.1. Using measured resistor values, calculate the current I_L and record in Table 13.1. Calculation: Turn on the supply and measure the voltage V_L. Then calculate the current I_L using the measured resistor value. Record the values in Table 13.1. Turn off the supply and change R_L to 47 Ohm. Record the measured resistor value calculate the resulting current I_L. Record the new value of I_L in Table 13.1. Calculation:

Explanation / Answer

d)

RL=47 ohm

Apply KVL in the loop

E=ILRS+ILRL=IL(RS+RL)

IL=E/(RS+RL)=10/(10K+47)=0.9953mA
