Relationship between V & I

V = IR
When the voltage increases the current also increases and vice versa.
The voltage and the current is used to determine the resistance of the circuit.
We can therefore deduce that V and I are dependant on one another.

R = v/I
Therefore v = IR
Therefore I = v/R


Conclusions to investigation

1. The higher EMF of the circuit will create a higher current, a higher potential difference and a higher resistance.
2. A lower potential difference and current will deduce a low resistance.
3. The graph cannot possibly have a constant gradient due to the presented the readings on the Voltmeter and Ammeter.
