Power Supply Digital Multi-meter Vcc +12 V Procedure Part 1- Simple Switch Circuit R 1 K Red LED Step 1.1 - Set the DMM to measure the resistance. Measure R1 and R2 resistance and enter the values in Result Sheet (T5.1) R 10 K Rp Vout ww Q Step 1.2 Set the power supply to 12 V. Construct the circuit shown in Figure 5.1. Make sure the Power supply is OFF. Pay attention to the direction of the LED. Set the DMM to measure DC Voltage. 10 K 2N3904 3 Vin Figure 5.1 Step1.3 Turn on the Supply and twist the potentiometer's knob all the way so LED becomes OFF. Step 1.4 Set the DMM to measure DC Voltage. Measure the voltage Vin (as indicated in the figure above) and enter the values in Col1, T5.2. Step 1.4 Measure the voltage VOUT (=VCE) and voltage across R2 (VR2 Jenter the values in Col3and Col5of T5.2. Step 1.5 Calculate the Ic and write it down in Col7, T5.2. VR2 Ic = R
