When copper is added to silver in small quantity so as to form an alloy, the resistivity of such an alloy is:

1. equal to the resistivity of copper
2. equal to the resistivity of silver
3. greater than the resistivity of copper
4. in between the resistivity of silver and copper

When copper is added to silver in small quantity so as to form an alloy, the resistivity of such an alloy is greater than the resistivity of copper.
