A surgical instrument includes a reusable base component including a handle and an electrically activatable modular component removably coupled to the base component. The modular component includes an end effector operable from the handle to treat tissue. The end effector is responsive to manipulation of the handle. A first energy storage component is disposed onboard the base component and is electrically coupled to a source of electricity. A second energy storage component is disposed onboard the modular component and is electrically insulated from the first energy storage component. The second energy storage component is arranged such that a current may be selectively induced in the modular component by delivery of electrical energy to the first energy storage component.
