Question

In an experiment to study the potential difference across a resistor and the current through it student recorded the following observations:





Potential difference V



1.0



2.2



3.0



4.0



6.4





Current I



0.1



0.2



0.6



0.4



0.6





On examine of the above observations the teacher asked the student to reject one set of the reading as the values were out of agreement with the rest. Which of the above reading can be readings can be rejected? Calculate the mean value of the resistance of resistor.

Answer 1

Answer:

Measured in Volts: **Potential difference (p.d.) is measured in volts (V) and is also called voltage. ... A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.
