Thus current gets doubled.
Ohm's law
When there is no physical change in the conductor then, the potential difference is directly proportional to the current flowing to the conductor.
Proportion
A proportion is an equation in which two ratios are set equal to each other.
Given
A 1.5-volt battery is removed and is replaced by a 3-volt battery.
To find
What happens to the current in a circuit?
How to get the relation?
The potential difference is directly proportional to the current flowing to the conductor.
Then
V ∝ I
V = RI .....1
Where V is voltage, I is current and R is resistance.
For V = 1.5, then equation will be
1.5 = R[tex]\rm I_{1}[/tex] .....2
For V = 3, then equation will be
3= R[tex]\rm I_{2}[/tex] .....3
Form equation 2 and 3
[tex]\rm I_{2} = 2 I_{1}[/tex]
Thus current gets doubled.
