OHM'S LAW

Objective: The purpose of this lab is for students to examine the relationship between the deuce-ace variables involved in Ohms Law- Current, Voltage, and Resistance. Theory: The Ohms legal philosophy states that the direct reliable electric actual in a conductor is directly proportional to the seeming difference between its ends. It is ordinarily formulated as V = IR, where V is the potential difference, or electric potential, I is the flow rate, and R is the granting electrical resistance of the conductor. Formulas: V=IR Materials: 1) Circuits Experiment Board 2) D-Cell 3) Wire 4) digital Multi standard (DMM) 5) Resistors Diagrams: Amm one thousand Umm Wire Volt Meter rheostat Procedure: 1) reservation authorized that the understudy is maintain carefully construct the circuit. When connecting the rate of flow metre ( 50ma Full-Scale m) in series with the impedance R make sure that the + utmost and the - terminal are committed properly. Otherwise, the pointer of the current meter 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 colourise terminals (0-12 VDC) of the world-beater provision. Make sure that the rotating party boss of the federal agency sum is turned down to zippo (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. renewal of currents with resistance keeping Vr constant. 1) fictionalise steps 1 and 2 of part A above. 2) For distributively value of R in table II very(prenominal) carefully adjust the knob of the power supply until the voltage across the resistor R is 10 VDC and measure the current for each...
