Question

draw a labelled circuit diagram to study the relationship between the current I flowing through a conductor and the potential difference V applied across its two ends state the formula correlating the ionic in a conductor and the vcross it also so this relationship by drawing a diagram what would be resistance of a resistor if the current flowing through it is 0.15 ampere when the potential difference across its 0.15 volt

Answer 1

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 directly proportional v  or i=v/r

r=resistance

As        V = 1.05 V

I = 0.15 A  

 V = IR  

 1.05 = 0.15 × R  

R = 1.05 / 0.15 = 7Ω

Answer 2

Answer:

As        V = 1.05 V

I = 0.15 A  

V = IR  

1.05 = 0.15 × R  

R = 1.05 / 0.15 = 7Ω
