Step-by-step explanation:
Current flow in conductor when it is connected to 12 V battery = 0.6A
We have to find current flow in conductor when it is connected to 4.5 V battery..
First of all we need to find resistance of conductor.
As per ohm's law, current flow through a conductor is directly proportional to the applied potential difference.
V ∝ I
Where, V denoted voltage and I denotes current
In first case :
➜ V = I × R
➜ 12 = 0.6 × R
➜ R = 12/0.6
➜ R = 20 \OmegaΩ
In second case :
➝ V' = I' × R
➝ 4.5 = I' × 20
➝ I' = 4.5/20
➝ I' = 0.225A
