(a(i))[1]
Define the term resistance.
(a(ii))[2]
Draw a circuit diagram to show the required connections between the components. Use the resistor symbol to stand for the nichrome wire.
(b(i))[1]
Show that the resistance of the wire is $5.00\,\Omega$.
(b(ii))[3]
Calculate, to three significant figures, the resistivity $\rho$ of the nichrome.
(b(iii))[2]
Calculate the percentage uncertainty in $\rho$.
(b(iv))[1]
Determine the absolute uncertainty in $\rho$.
