Receptors

The receptors convert stimuli, such as light, into electric signal (action potentials).

For example the (retina of the) eye is a receptor. When light enters the eye, electric signal (action potentials) is generated in the nerve from the eye (optic nerve).

Receptors {=generate electric signal (action potentials) when stimulated ~change activity by the electric signal (action potentials) it receives}.

Electric signals (action potentials) are generated when {=receptors ~effectors} are stimulated.
