National defense is a classic example of a public good as it is non-excludable and non-rivalrous, meaning that it cannot be withheld from anyone and its consumption by one person does not diminish its availability to others. Telephones and electricity are both private goods as they are excludable and rivalrous, meaning that individuals can be excluded from using them and their consumption by one person can reduce the amount available to others.
