On Friday, October 16, 2020, Don Bosco Tech (DB Tech) Nalagarh hosted an enlightening guest lecture on 'Direct Current, Alternating Current, and Electric Safety.' The session was graced by the presence of Mr. Raj Kumar, a seasoned electrician from Raj Electrical Work, Panjehra. Delivered via Google Meet to thirteen eager trainees and attended in person by four students at the DB Tech Centre, the event blended virtual and physical participation seamlessly.

Mr. Raj Kumar delved into the intricacies of Direct Current (DC) and Alternating Current (AC), captivating his audience with his detailed explanations. He elucidated that when a battery is connected to a closed electric circuit, it generates a steady electric flow known as Direct Current (DC), which travels unidirectionally. In contrast, he described how power plants use electric generators to produce Alternating Current (AC), characterized by electrons oscillating back and forth due to a continually changing voltage difference. This oscillation means the current reverses directions multiple times each second, leading to varying quantities of current and voltage.

To deepen the understanding, Mr. Raj explained the concepts of peak voltage and peak current, the maximum values attained by voltage and current, respectively. He also highlighted the practical application of root mean square (RMS) voltage and current, essential for electric companies to measure and charge for the average power consumption of households and businesses.

In addition to the technical insights, Mr. Raj emphasized the critical importance of electric safety in both domestic and industrial settings. He stressed the need for heightened awareness and adherence to Standard Operating Procedures (SOPs) to prevent accidents. Sharing real-life examples, he illustrated how mishaps could be averted by following SOPs, thus safeguarding humans, animals, and property. He also briefed the students on the expectations of the Energy Department for the upcoming Electric Safety Week Campaign.

The lecture concluded with a heartfelt vote of thanks to Mr. Raj Kumar for his invaluable contribution. The session not only enriched the knowledge of the attendees but also underscored the vital role of safety protocols in the electrical domain, leaving a lasting impact on the future electricians.
