Electrical current comes in different forms depending on the source creating the voltage.
Current that flows in only 1 direction all the time is called direct current (DC) Batteries and solar cells produce direct current
Currently that regularly reverses direction is alternating current. generator Power company (Utility)
A circuit is a complete path through which current can flow.
Any break in the circuit will prevent the flow of electricity throughout the whole circuit. (open circuit)
There are two basic types of pathways that can be set up for electric current to flow. A series circuit is connected so that there is only 1 pathway through which current can flow A parallel circuit is connected to provide each component with its own pathway.
What is the name of a current That flows in only one direction? Direct current (DC)
Are these bulbs connected in a series or a parallel circuit? Parallel
What type of current is flowing through this circuit? Direct current
A B Which of these circuits is a series circuit? A
The property of storing magnetic energy is called inductance Inductance is measured in henries. The purpose of the inductor is to smooth out current changes.
Resistors: Function is to control the flow of current.
Resistors have a certain specified resistance measured in ohms ( ) Some resistors are variable, meaning the Resistance can be changed. This type of resistor is called a potentiometer, and is the type of component used as a volume control.
Diodes allow current to flow in only 1 direction, meaning it can turn an ac current into a dc current by stopping the flow in the wrong direction. LED=Light Emitting Diode
Transistors use voltage or current signals to control current flow. Transistors can be used as either an electronic switch or an amplifier. Gain is the term used that describes a transistor’s ability to amplify an signal.
