4.2.4a Resistance

Wire A and wire B are made from the same metal.

The table gives information about the two wires:

	Length / $m\text{m}$	Cross-sectional area / $mm2\text{mm}^2$	Resistance / $Ω\Omega$
Wire A	2.0	0.50	3.0
Wire B	1.5	0.25

What is the resistance of wire B?

$Ω1.1\ \Omega$

$Ω2.0\ \Omega$

$Ω4.5\ \Omega$

$Ω8.0\ \Omega$
