Understanding Electricity: The Basics of Voltage, Amps, and Resistance
Electricity is the movement of electrons from one atom to another, creating a flow that powers our devices. Three key factors influence this flow: voltage (the pressure on electrons), amps (the volume of flow), and resistance (the hindrance to that flow). To create a functioning circuit, it must be a closed loop, allowing electrons to move. The relationship between these factors is governed by Ohm's Law, where voltage (V) equals amps (A) times resistance (R). Understanding these concepts is crucial for anyone working with or studying electricity.

What is it?? • Movement of electrons from one atom to another • Trying to create a balance
Three factors • Voltage • Pressure on the electrons. • Amps • Measurement of volume of flow. • Resistance • Resistance to flow.
What does it take? • To make amps, circuit must be a loop • The more electrons moving means more work done • The more pressure (voltage) applied means more work done
Measuring • Voltage • Live or dead circuit - whatever you want • Amps • Must be in ‘series’ in a live circuit • Resistance (Ohms) • Circuit MUST be dead
Relationships • The three measurments all work together • One cannot change without affecting another
Ohm’s Law • V = AxR • A = V / R • R = V / A V AXR
