Some believe the first such invention occurred in 1944. However, there is strong evidence that the Atanasoff-Berry computer was invented and "reduced to practice" in 1939 at Iowa State University, and that portions were copied by the ENIAC inventors. This was determined in 1973 by a federal court presiding over a patent case between Honeywell and Sperry Rand. In similar developments, Colossus was the first electronic computer (that was developed by the British) to crack the LORENZ codes used by the German high command. The existence of Colossus remained a secret long after WWII. Until recently ENIAC was thought to be the first (although later than Atanasoff-Berry), but the secrecy of Colossus was finally lifted and we find it (and 9 others) were first operational in Jan 1944 while various portions of ENIAC were made operational in the period of June 1944 through October 1945. There are yet others who believe earlier calculators qualify as the first "digital computers".

The electronic computer was not invented in 1641, there was no electronics in 1641. The electronic computer was invented in the 1940s. Charles Babbage did invent the programmable digital computer, the Analytical Engine, but it was mechanical not electronic.

No, the first electronic digital computer was made in 1942. Its invention was about 1937.Electronic digital computers have been manufactured for sale since 1950.

Charles baggage invented the digital and automatic computer.
He invented the first electro digital computer
Uncertain, but sometime in the early 1950s when an off the shelf electronic analog computer was interfaced to an electronic digital computer.
Electric Light Bulb
Never, because it did not preexist its use by humans. The electronic computer (both digital & analog) was invented.
