Corrosion is the irreversible damage or destruction of living tissue or material due to a chemical or electrochemical reaction.
Nuclear fusion in the core tries to blow the star apart. Gravity holds it together. Whoever designed that system really knew what he was doing. I'm kinda grateful to him.
The total resistance is 420 ohm.
A circuit with resistive elements of 220, 100, 57, and 43 produce what total resistance
R= 220+ 100+ 57+ 43
= 420 Ω
What is resistance and its types?
Resistance is a measure of the opposition to current flow in an electrical circuit also known as ohmic resistance or electrical resistance. Ohms are measured as resistance, symbolized by the Greek letter omega (Ω). The ratio of the applied voltage to the current through the material is then known as resistance.
What causes resistance?
An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.
