About Charles Francis Dalziel
Charles Francis Dalziel was born on April 1904 in Nebraska, United States, and died on April 12, 1986. He was an esteemed professor of Electrical Engineering at the University of California, Berkeley, from 1947 to 1971. He was married with children and spent the majority of his professional life in Berkeley, California, where he passed away.
Dalziel's work was predominantly focused on the study of electric shock hazards and safety measures. His drive towards these studies came from an inherent desire to understand the effects of electricity on the human body and to develop standards for electrical safety that could prevent electrical accidents.
Dalziel's Discoveries
Dalziel's research led to a better understanding of the effects of electric shock on the human body. He was particularly interested in exploring how electrical currents of different intensities and durations could cause different types of injuries. This work was pioneering in the field of electrical safety.
Dalziel faced challenges during his research due to the complexity of the human body's response to electricity. However, his meticulous and rigorous experiments led to numerous valuable insights.
Dalziel's Key Achievements
Dalziel is most well-known for his research into electrical injuries and his contributions to electrical safety standards. His work forms the basis of many current regulations and guidelines in the electrical industry.
Additionally, Dalziel was the recipient of the IEEE's Edison Medal in 1972 for his exceptional contributions to electrical safety.
Dalziel's Formulas
Dalziel's studies led to the development of key equations that describe the effect of electric current on the human body, such as:
The Dalziel curve for fibrillation:
Where:
- It: The current at time 't' that can cause ventricular fibrillation.
- t: Time in seconds.
