Procedure VPSI 82052 WWW R₁ B A S₁ 4₁ A Th A 1₂ R₂120052 A B S₂ Figure 3.3 VPS2 R₁ 2200Ω 1. Connect the circuit in figure 3.3 switch S, and S₂ are in position B and "OFF" power source. 2. "ON" the power source (PS1) given Vest = 15 V. 3. Check the switch S₂ is in position B then push switch S, to position A. Measure 1₁ 12 13 and V₁ V₂ V3 that dropping R₁, R₂ and R, (Current and voltage that measured must has position or negative mark). 4. Push switch S, to position B and "ON" PS2 given Vps2 = 10 V. 5. Push switch S₂ to position A and measure I and V same as step 3. 6. Now S₂ is in position A push S, to position A and measure I and V same as step 3. 7. "OFF" the power source. Table 3.3 Switch S₁ A B A Switch S₂ B A A 4₁ 1₂ 13 V₁ V₂ V3 Analysis the result part 2 1. Analyze the circuit in figure 3.3 and use superposition method to finding 1₁ 23 and V₁, V₂, V₁ 2. Compare the experiment result and calculated. Questions part 2 1. Why mark +, - in current are important for measuring. 2. If both sources are reversed what happens to current flowing through R₂.
