Verified Facts
- Before Volta's invention, electricity was only understood as brief, uncontrollable static sparks (like lightning).
- This continuous power source was the absolute prerequisite for the telegraph, the electric motor, and eventually all of modern computing.
- The unit of electrical potential—the "Volt"—is named in his honor.
