Objective: The purpose of this lab is for students to investigate the relationship mingled with the triad variables involved in Ohms Law- Current, Voltage, and Resistance. Theory: The Ohms law states that the site reliable stream in a conductor is promptly proportional to the probable difference between its ends. It is usually explicate as V = IR, where V is the potential difference, or electric car potential, I is the authentic, and R is the granting immunity of the conductor. Formulas: V=IR Materials: 1) Circuits try out Board 2) D-Cell 3) Wire 4) Digital Multi standard (DMM) 5) Resistors Diagrams: Amm one honey oil Umm Wire Volt Meter rheostat Procedure: 1) qualification genuine that the shift is vindicated carefully construct the circuit. When connecting the contemporary meter ( 50ma Full-Scale meter) in series with the impedance R make sure that the + lowest and the - terminal are affiliated properly. Otherwise, the pointer of the curren t meter will deflect in the wrong direction when current passes through the circuit and this could in truth well damage the meter itself. 2) Connect points A and B of the circuit to the red and discolour terminals (0-12 VDC) of the world-beater provision. Make sure that the rotating knob of the power supply is turned down to cipher (fully clockwise). Adjust the decade granting immunity box to 100 ohms.
3) By carefully turning the power supply clockwise with the switch closed measure the potential across the resistor R when the current is objurgateed from 5ma to 50ma in increments of 5ma*. B. Variation of cu rrents with resistance keeping Vr constant. ! 1) recite steps 1 and 2 of part A above. 2) For for each one value of R in table II real carefully adjust the knob of the power supply until the voltage across the resistor R is 10 VDC and measure the current for each...
