thusRp = R1R2/R1+R2Electrical power is given by P = IV = I2R (because remember: V = IR)Method:First, use voltmeter and ammeter to measure dc voltage and current. Begin by using the DMM to measure resistances of 4 resistors and record the values in table 1. Now connect the circuit as seen in figure 1 on pg. 23. With DMM2 set to 5V, measure the voltages V1, V2, V3, V4across R1,R2, R3, R4. Use DMM1 to measure the current. Record your values in table 2. Next connect the circuit as seen in figure 2(a) on pg. 24 (in series). Turn the power supply on to 5V. Observe the brightness of the bulbs, which act as resistors and record the value of the current in table 3. Repeat this same step for the remaining figures on pg. 24. The third measurement involves resistors in a parallel connection. Begin by connecting the circuit as shown in figure 3(a) on pg. 25. Turn the power supply on to 5V and observe the brightness of the bulbs and record the value of the current in table 4. Repeat the same step for the remaining figures on pg. 25. Lastly, measure the current of resistors in both a series and parallel fashion. Connect the circuit like that seen in figure 4 on pg. 26. Turn on the power supply to 5V and observe the current and brightness of the resistors. Record the results in table 5. Now change the power supply to 10V. Repeat the previous step but this time, remove a light bulb (resistor) each time and record the results in table 5.
