OHM'S LAW

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 presently reliable stream in a conductor is directly proportional to the probable difference between its ends. It is usually hypothesize as V = IR, where V is the potential difference, or galvanizing potential, I is the present-day(prenominal), and R is the granting immunity of the conductor. Formulas: V=IR Materials: 1) Circuits investigate Board 2) D-Cell 3) Wire 4) Digital Multi standard (DMM) 5) Resistors Diagrams: Amm one gibibyte Umm Wire Volt Meter rheostat Procedure: 1) devising certain(a) that the substitution is vindicated carefully construct the circuit. When connecting the veritable meter ( 50ma Full-Scale meter) in series with the impedance R make sure that the + lowest and the - terminal are machine-accessible properly. Ot herwise, the pointer of the current meter will deflect in the wrong direction when current passes through the circuit and this could genuinely 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 nothing (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 electromotive force across the resistor R when the current is objurgateed from 5ma to 50ma in increments of 5ma*. B. Variation o! f currents with resistance keeping Vr constant. 1) recap steps 1 and 2 of part A above. 2) For each value of R in table II really carefully adjust the knob of the power supply until the voltage across the resistor R is 10 VDC and measure the current for each...
