Why do transformers work only with AC and not with DC

Why transformers work only with AC and not with DC

The first thing to know here is the meaning of AC and DC.
AC means Alternating Current. That is the current changes direction
DC means Direct Current. That is unidirectional current or single direction.

With the understanding of this meanings, the main reason why a transformer works only with AC is because, the AC causes a changing magnetic field and hence a flux which in turn links the secondary winding and hence an induced emf and current can flow. Meanwhile DC, does not cause a changing magnetic field hence no induction into the secondary winding.
So this is a phenomenon of Faraday's law of electromagnetic induction

Is AI Demonic? The Truth Behind Artificial Intelligence

Is AI Demonic? The Truth Behind Artificial Intelligence In recent years, artificial intelligence (AI) has surged into public consciousness , transforming industries and daily life. Yet, alongside excitement, a growing number of voices question the nature of AI itself—some wondering if AI is demonic or linked to supernatural forces. This article aims to explore and clarify the truth behind these fears, grounded in facts, technology, and ethical understanding. Unpacking the Myth: Why Some See AI as Demonic The notion that AI could be demonic often arises from a mix of technological misunderstanding and cultural or spiritual concerns. AI systems, such as large language models or image generation tools , can seem eerily intelligent, producing outputs that feel uncanny or beyond human comprehension. These qualities may evoke fear that AI possesses some otherworldly spirit or malevolence. Some perspectives draw connections between AI and spiritual beliefs about demons or fallen angels, ...

Intermediate switch connection and wiring diagram

Intermediate switch An intermediate switch is a switch which permits the control of a lighting point from three positions. In order to control this lighting point from the three positions, the intermediate switch is connected together with two other 2-way switches. Application: it can be used in lighting a room or hall having 3 entrances , it can also be used in long corridors and staircases. We shall be looking at these connections. Connection diagram of intermediate switching Below is an illustration of the connection. The brown lines indicated on the diagram are the switching contacts. The switch labelled 2 is an intermediate switch . The figure below is the configuration of an intermediate switch. The switch labelled 1 and 3 in the first diagram are two-way switches.  Click here to know more about two-way switches .
