The Digital multimeter is inserted with the DC power supply, using the banana the probes for connection. The DC power supply is then connected to the circuit. Experimental Procedure For procedure A after the setup, set the digital multimeter to milliampere by turn m A then turn on the DC power supply. Set voltage and current to zero by pressi knob and the current knob and set to 0.000 Volts and Amps. Set the voltage to 1 slowly increase in increments of 0.010 until 15.00 V has been reached. The first only need 0.020 A or 0.030 A, after the reading stabilizes be sure to record the measured by the Digital multimeter. Then set the current to 0.000 A on the DC turn it off. Calculate and record the results then move on to circuits two, three a
