5.8. REVERSE ENGINEERING 1. The following equations describe a DC circuit. -1 (51 92) +7.000 V -1 (68 0) =0 +1, (68 0) + 1 3 (10 92) -3.00 V =0 h+13 -12=0 2. Draw the circuit diagram. 3. Reconstruct the circuit with the PhET App. 4. Identify the physical meaning of each unknown on your circuit diagram. 1. Measure the current passed through each of the junction. 2. Measure the potential drop across each of the resistor. 3. Calculate the predicted values (solving the simultaneous equations). 4. Record the predicted and simulated voltages on Table 4.3. 5. Calculate the percentage differences. V (predicted) V (simulated) % difference R RA
