Resistance is the measure of opposition to the flow of electric current in a material.
Resistance is measured in ohms (Ω).
It is caused by the collisions of electrons with atoms and other electrons in the material.
Resistance can be influenced by factors such as temperature, length, and cross-sectional area of the material.
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltag...
The unit of resistance is ohm (Ω).
The unit of resistance is named after the German physicist Georg Simon Ohm.
Resistance is a measure of how much a material or device opposes the flow of electric current.
The symbol for ohm is the Greek letter omega (Ω).
Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.
Common examples of resistance include resistors, light bulbs,
AC and DC shocks can both be dangerous, but AC shocks are generally considered more dangerous.
AC shocks can cause muscle contractions, making it difficult to let go of the source of the shock.
AC shocks can also cause ventricular fibrillation, a potentially fatal condition where the heart's rhythm becomes irregular.
DC shocks are more likely to cause burns and tissue damage at the point of contact.
However, the severity o...

The last % refers to the percentage of completion of your most recent project or task.
The last % is a measure of how much of the project or task has been completed.
It can be calculated by dividing the amount of work completed by the total amount of work required.
For example, if you have completed 80% of a project, your last % would be 80%.
