A multimeter or a multitester, also known as a VOM, is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage, current, and resistance. Analog multimeters use a microammeter with a moving pointer to display readings.
This presentation contains information about some basic electrical parameters such as Voltage, Current, EMF, PD, Electric Power, Energy Ideal & Practical Sources, Types of Resistance, Heating Effect, Magnetic effect & Chemical effect of Electric Current etc.
Electrical instruments are instruments that use the mechanical movement of electromagnetic meter to measure voltage, power, current… Electrical technicians require electrical measurement equipment to check the electrical activity and to detect the presence of voltage or current. By using this instrument we can measure electrical parameters such as voltage, frequency, current, power factor, and resistance. Electrical measurements are depended upon either current or voltage while measuring the frequency we will be measuring the frequency of a current signal or a voltage signal.

Scope
It is not possible to build practical computers, cell phones, personal data devices, cars, airplanes, industrial processes, and other everyday products without power electronics.
Alternative energy systems such as wind generators, solar power, fuel cells, and others require power electronics to function.
Technology advances such as electric and hybrid vehicles, laptop computers, microwave ovens, flat-panel displays, LED lighting, and hundreds of other innovations were not possible until advances in power electronics enabled their implementation.
Although no one can predict the future, it is certain that power electronics will be at the heart of fundamental energy innovations.

witter is a microblogging and social networking service owned by American company Twitter, Inc., on which users post and interact with messages known as "tweets". Registered users can post, like, and retweet tweets, while unregistered users only have a limited ability to read public tweets. Users interact with Twitter through browser or mobile frontend software, or programmatically via its APIs. Prior to April 2020, services were accessible via SMS.[9] Tweets were originally restricted to 140 characters, but the limit was doubled to 280 for non-CJK languages in November 2017.[10] Audio and video tweets remain limited to 140 seconds for most accounts.
Twitter was created by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams in March 2006 and launched in July of that year. Twitter, Inc. is based in San Francisco, California and has more than 25 offices around the world.[11] By 2012, more than 100 million users posted 340 million tweets a day,[12] and the service handled an average of 1.6 billion search queries per day.[13][14][15] In 2013, it was one of the ten most-visited websites and has been described as "the SMS of the Internet".[16] By the start of 2019, Twitter had more than 330 million monthly active users.[17] In practice, the vast majority of tweets are written by a minority of users.[18][19]
On April 25, 2022, the Twitter board of directors agreed to a $44 billion buyout by Elon Musk, the CEO of SpaceX and Tesla, potentially making it one of the biggest deals to turn a company private.[20][21] Musk said on July 8, 2022, that he was terminating the deal, claiming that the social media company had failed to provide information about fake accounts on the platform.[22] Twitter board chair Bret Taylor subsequently pledged to pursue legal action against Musk, launching a lawsuit against him in the Chancery Court of Delaware on July 12.[23] In early October, 2022, Musk reversed his position, again -- saying he would go ahead with the deal at the originally agreed $44 billion price.witter is a microblogging and social networking service owned by American company Twitter, Inc., on which users post and interact with messages known as "tweets".

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
