Chapter 5 Flashcards
What is an electric circuit?
A closed loop that provides a path for the transfer of electrical energy from a power source to an electrical component
Whata does a circuit require?
A source of electricity, a lode / component (converts electrical energy into other forms of energy and wires
What is a circuit diagram?
A visual representation of the arrangement of the different parts of a circuit
What is an electrical current?
A measure of the rate of flow of charges passing through a point along the wire
What is electrical current meaasured in?
Amps
What is voltage?
A measure of the amount of energy supplied to the charges by the power source (or amount of energy used by the component).
What is voltage measured in?
Volts
What is resistance?
A measure of how difficult it is for an electric current to flow through a material or component
What is resistance measured by?
A multimeter
What is the units for resistance?
Ohms
What are conductors?
Materials that have very low resistance and allow electric current to pass through them easily
What are insulators?
Materials that have high resistance and prevent electric current to pass through easily
What is Ohm’s law?
Resistance = Voltage / Current
What is a series circuit?
A circuit where all the components are connected one after another to form a single loop. The voltage is shared between each component
What are the good things about series circuits?
Easy to build, less materials
