Answer:

[tex]R=9\ \Omega[/tex]

Explanation:

Given that,

Current, I = 2 A

Voltage across the resistor, V = 18 V

We need to find the value of resistance of the resistor. Let the resistance be R. We can find it using Ohm's law i.e.

V = IR

Where

R is the resistance of the resistor

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{18}{2}\\\\R=9\ \Omega[/tex]

So, the resistance of the resistor is equal to [tex]9\ \Omega[/tex].
