The resistance of wire B will be D. 1/2R
<h3>What is resistance?</h3>
It should be noted that resistance simply means the measure of the opposition to the current flow that's in an electric circuit.
Based on the information given, the resistance will be calculated thus:
= 2L/4A
= 1/2pL/A
= R/2
Therefore, the resistance of wire B will be D. 1/2R
