30. Ro R A X+ voltage eliminator Ro+ Knowre Resistance A Ammeter v + voltmeter (K) Runknown resistance. каксу i. ii. iii. Design a lab to calculate the resistance R which is unknown and Vo=10 V, Ro= goes from 2 Ohm, 4 ohm...... till 16 ohm. For Ro= 2 ohm, V=4 volt. Use this information to design the data table for V and I through R. Draw a data tables to calculate current, Voltage across Ro, and then calculate R by plotting graph between voltage and current through unknown resistance R.. iv. Write the probable causes of error and how to solve them? [11 marks]
