# Electricity

## What is electricity?

Electricity is the set of physical phenomena associated with the presence and flow of electric charge.

Atoms the smallest particles of an element that has all the elements properties

Electrons Negatively charge

Current electricity is electricity that flows from one place to another

Static electricity a stationary electric charge, typically produced by friction, that causes sparks or crackling or the attraction of dust or hair.

## Ohm's Law

V stands for Voltage

R stands for Resistors

I stands for the current flow of electrons

These 3 defines the relationship between the voltage, current, and resistance in an electric circuit: I = V/R. The current is directly proportional to the voltage and inversely proportional to the resistance.

if Voltage increases and Resistance is constant, the current will also increases.

but if Resistance increases and V is constant the current flow will decreases.

V increases I increases

V decreases I decreases

R increases I decreases

R decreases I increases

## Circuit

4 parts that make up a single series circuit are resistor, wire, battery, load.

we need resistor in all circuit to balance and control the current flow of electricity. so if voltage increases, you have to increase the resistors too so that the load will not blow up nor explode.

single series circuit is a circuit with only one path from the source through all of the loads and back to the source. this means that all of the current in the circuit must flow through all the loads.

Parallel circuit has more than 1 resistors and gets its name from having multiple paths to move along.

what is the differences between conductor and insulator?

CONDUCTOR: those objects which can pass electricity through them is known as conductors. the conductors can pass electricity through them due to free electrons present in them. for example: iron, copper, aluminium etc.
INSULATOR: those objects which can not pass eletricity through them is called insulator. the insulators can't pass electricity due to less or absence of free electrons. for example paper, wood, rubber etc.

Conventional current flow is when electric charge moves from positive side of the battery to the negative side of the battery.

actual current flow (electron flow) is when electric charge moves from negative side of the battery to the positive side of the battery.
