1.	Draw a labelled circuit diagram to study the relationship between the cunent (I) flowing through a conductor and the potential difference (V) applied acro its two ends. State the formula conelatlng the I in a conductor and the V acroa it. Also show their relationship by drawing a diagram. What would be the resistance of a resistor if the current flowing through it is 0.15 A when the potential difference across it is 1.05 V ?
Answer» Solution : The formula STATES that the current passing through a conductor is directly proportional to the POTENTIAL difference across its ends, PROVIDED the physical CONDITIONS LIKE temperature, density, etc. remain unchanged . This is Ohm.slaw `I prop V or I =(V)/(R)` `V= pm IR `. R is called resistance of the conductor As V= 1.05 V I = 0.15 A V =IR `1.05 =0.15 xxR ` `R =(1.05)/(0.15) = 7 Omega`
