Solution:
To find the potential, let's apply ohm's law.
=> V=IR
Here:-
Current remains same in series connection but potential varies, so value of current will also remain 0.5 A across 4Ω resistor.
Put values in formula.
=> V=(0.5 A)(4Ω)
=> V=2 A.Ω
Replace A.Ω with v
=> V=2v
So the potential difference across 4Ω resistor is 2v.
Rest of all given values are useless.
