What is the device used for converting AC to DC called? The device used for converting alternating current (AC) to direct current (DC) is called a rectifier. A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, into direct current (DC), which flows in only one direction. The process is known as rectification. Rectifiers have many uses in a variety of electrical appliances, electronics and technology sectors. Their most notable use is in power supplies where they convert the AC voltage into a steady DC voltage. They are also commonly used in electronic devices such as radios and televisions to detect the audio and video signals from radio and television broadcasts. Rectifiers are fundamentally crucial for several gadgets, devices and appliances that rely on DC for their operations. Since most households, offices, industries, etc., receive AC power supply, it becomes necessary to convert the same into DC for thes...
On the other hand, positive charges, +5 micro coulombs in this case, are where the electric field lines originate or begin. The field lines radiate out from the positive charge. Here, given that this charge is greater than the negative charge, more field lines will originate from this charge. The pattern of these lines also suggests the interaction between these two charges. They would move along the electric field lines from the positive charge towards the negative charge, representing the motion of a positive test charge if it were released near the positive charge. Since field lines are denser closer to the charges and less dense further away, this indicates that the electric field is stronger near the charges and weakens with increasing distance. Moreover, these field lines never cross each other. Each line must begin on a positive charge and end on a negative charge, making an unbroken curve. It is crucial to keep in mind this fundamental concept while drawing electric field...
