Electrical circuit Laboratory Expertment No. (T) Ohm's Law Procedure: 1. Connect the circuit shown in Fig. below, the value of R=1k Q. Increase the value of voltage and measure current in each step, record it in table below. Voltagelvolt) Current(amper) I (theory) 2. Repeat step (1) with change the value of resistance R=330 N, measure current and record it in table below. Voltage(volt) Current(amper) I (theory) 3. Repeat step (1) with change the value of resistance R=680 2, measure current and record it in table below. Voltagelvolt) Current(amper) I (theory) 4. Using the measured current from tables 1, 2 and 3, create a plot of current versus voltage .voltage is the horizontal axis and current is the vertical axis. GRAPH: Obtain value of "R' via slope of "V' vs 'I= AB Slope BC Slope=A V/A I=V2-V1/lz-I Percentage error= I Measured- I theory / I theory * 100% Questions: 1-is there a linear relationsip between current and voltage? 2- Why should the graphic be a straight line in step (1)?
