6.) First, define electrical resistance:
Electrical resistance, the degree to which a passing electric current is dissipated into heat

Thus, since the heating element is designed to dissipate current into heat, it has a higher resistance.

7.) Use Ohm's law: R = V/I.
R = 3 volt / .10 amp = 30 ohms
