Objective: The purpose of this lab is for students to investigate the relationship in the midst of the triad variables involved in Ohms Law- Current, Voltage, and Resistance. Theory: The Ohms law states that the steer reliable stream in a conductor is immediately proportional to the probable difference between its ends. It is usually suppose as V = IR, where V is the potential difference, or galvanizing potential, I is the actual, and R is the granting immunity of the conductor. Formulas: V=IR Materials: 1) Circuits try Board 2) D-Cell 3) Wire 4) Digital Multi standard (DMM) 5) Resistors Diagrams: Amm one mebibyte Umm Wire Volt Meter rheostat Procedure: 1) reservation legitimate that the riff is vindicated carefully construct the circuit. When connecting the authoritative meter ( 50ma Full-Scale meter) in series with the impedance R make sure that the + lowest and the - terminal are connected properly. Otherwise, the pointer of the current m eter will deflect in the wrong direction when current passes through the circuit and this could really 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 slide fastener (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 emf across the resistor R when the current is objurgateed from 5ma to 50ma in increments of 5ma*. B. Variation of cur rents with resistance keeping Vr constant. ! 1) fictionalize steps 1 and 2 of part A above. 2) For each(prenominal) value of R in table II rattling carefully adjust the knob of the power supply until the voltage across the resistor R is 10 VDC and measure the current for each...
