Question

What is it and who invented it?
1. Dry Cell
2. Simple Cell
3. Dynamo
4. Capacitor

Answer 1

• Answer:
• The dry cell is one of many general types of electrochemical cells. A dry cell has the electrolyte immobilized as a paste, with only enough moisture in it to allow current to flow. Unlike a wet cell, a dry cell can operate in any orientation without spilling, as it contains no free liquid.
• simple cell is a device that converts chemical energy into electrical energy. A simple electric cell consists of two electrodes (two different metals) and an electrolyte solution (acid or alkali solution or salt solution)
• Steven Frayne, better known by his stage name Dynamo, is a British magician born in Bradford, West Yorkshire. His television show Dynamo: Magician Impossible ran from July 2011 to September 2014, and saw him win the Best Entertainment Programme award at the 2012 and 2013
• A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance.

Answer 2

Answer:

1. Carl Gassne 2. Robert Hookel 3. 3. Zenobe Theophile Gramme 4. 4. Pieter van Musschenbroek

Explanation:

1. Carl Gassner

In 1888, a German called Carl Gassner invented a battery where there was no risk of the solution spilling. Because the battery would not spill even though it contained a liquid, Gassner's invention became known as the “dry cell” or “dry battery.”

2. Robert Hooke

The cell was first discovered by Robert Hooke in 1665 using a microscope. The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s.

3. Zenobe Theophile Gramme

(1826 – 1901) invented the first industrial generator, or dynamo. A deceptively simple-looking machine, it consisted of 30 coils wrapped around a spinning ring of iron.

4. Pieter van Musschenbroek

capacitor is a device for temporarily storing electric charge. What is considered to be the very first capacitor was called the Leyden jar, which was invented by Pieter van Musschenbroek in 1746 at the University of Leyden (or Leiden) in Holland
