Electricity

• In a parallel circuit, the total resistance is less than the smallest individual resistance.
• When an electrically charged object touches something that isn't charged, it will transfer some of its charge to the other object.
• Insulators prevent the flow of electric charge, though they can become conductors under certain conditions.
• Electric charge can be transferred from one object to another by contact or induction.
• Conductors allow the flow of electric charge.
• A power source, such as a battery or generator, provides electrical pressure or voltage.
• The current is the flow of electrons around a circuit.
• The difference in electric potential between two points is called voltage.
• A series circuit is a circuit in which the components are connected in a single loop, so the current flows through each component in sequence.
