Heating Element
• The heating plate acts as a heating element.
• The conductor material has a high resistivity,
melting point and is durable.

Connecting Wire
• The connecting wire consists of fine
metal wires.
• Copper wire is used because copper has
low resistivity which prevents the wire
from heating up too quickly when current
flows through it.

Different conductors have different resistivities. Likewise, non-conductors, semiconductors
and superconductors have different resistivities as well.
