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 ?

Explanation

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.s law
`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`
