Objective: The purpose of this lab is for students to investigate the relationship betwixt the triad variables involved in Ohms Law- Current, Voltage, and Resistance. Theory: The Ohms law states that the take in reliable stream in a conductor is instanter proportional to the probable difference between its ends. It is usually conjecture as V = IR, where V is the potential difference, or electric potential, I is the underway, and R is the granting immunity of the conductor. Formulas: V=IR Materials: 1) Circuits examine Board 2) D-Cell 3) Wire 4) Digital Multi standard (DMM) 5) Resistors Diagrams: Amm one railway yard Umm Wire Volt Meter rheostat Procedure: 1) do authorized that the thrash is vindicated carefully construct the circuit. When connecting the afoot(predicate) meter ( 50ma Full-Scale meter) in series with the impedance R make sure that the + lowest and the - terminal are committed properly. Otherwise, the pointer of the current mete r will deflect in the wrong direction when current passes through the circuit and this could rattling 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 set (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 potentiality across the resistor R when the current is objurgateed from 5ma to 50ma in increments of 5ma*. B. Variation of curren ts with resistance keeping Vr constant. 1) ! assume steps 1 and 2 of part A above. 2) For each(prenominal) value of R in table II truly carefully adjust the knob of the power supply until the voltage across the resistor R is 10 VDC and measure the current for each...
