Answer: 4 ohms
Explanation:
The relationship between potential difference and current in a resistor is given by Ohm's law:
[tex]V=RI[/tex]
where
V is the potential difference
R is the resistance
I is the current
In this problem, we have:
V = 8 V (potential difference across the resistor)
I = 2 A (current in the resistor)
Therefore, we can re-arrange the equation to find the resistance:
[tex]R=\frac{V}{I}=\frac{8}{2}=4 \Omega[/tex]
