Electricity

Electricity is the movement of charged particles, primarily electrons, through a conductive medium

Value of one coulomb equivalent to in terms of electric charge

1 coulomb is the amount of electric charge that corresponds to the quantity of charge moved by a current of one ampere in one second.

TRUE OR FALSE: current is not something that literally flows. Instead, it is a measure of the flow of charge at a specific point in the circuit. It exists at that point as the rate at which charge is passing through.

True

Voltage is the electrical potential difference between two points in a circuit, measure in Volts (V), and acts like ______ electrons through the circuit

pressure pushing

resistance and current relationship

• R opposition to I

• inverse relationship

• higher resistance results in less current flowing through the circuit.

role of a light bulb filament regarding resistance?

A light bulb filament has high resistance, limiting the current flow and converting electrical energy into heat and light.

Ohm’s law

relationship between voltage (V), current (I), and resistance (R) with the formula V = IR, allowing for the calculation of unknown electrical quantities.

Series Circuit

components are connected end-to-end with the same current flowing through all components

parallel

components are connected across the same two points sharing the same voltage,

what happens in electric current in series circuit

• the current is distributed the same in all components

voltage in series circuit

• Sum of the voltage drops across each component equals the total supply voltage.

voltage in parallel circuit

it is the same all across the components

current in parallel circuit

 Sum of the currents through each component equals the total current from the power source
