How to draw an ER diagram where there are 2 entities with exactly same attributes

Question

Each appliance is classified as either: Kitchen appliances, Entertainment appliances, and it’s important to keep track of their type.

Kitchen appliances and Entertainment appliances have details about weight and dimensions. But, for entertainment appliances also store details about power consumption and display size.

Some appliances, called Smart appliances, have both kitchen and entertainment features.

Draw an ER diagram for this. What I am confused about is how to model Entertainment appliances and Smart appliances because both of them would be having the same attributes.

Answer 1

Honestly, i'd just make one entity and then add an extra attribute called "type"
