Switches
What are switches for?
Switches are used to control the flow of elctricity in a circuit
What is a Diode?
A diode is a semiconductor device that essentially acts as a one-way switch for current.
What is the purpose of a Zener diode?
Zener diodes are used for voltage regulation, as reference elements, surge suppressors, and in switching applications and clipper circuits.
What are Capacitors for?
Capacitors have the ability to store and discharge electricity very quickly
What is the main purpose of an integrated circuit?
an amplifier, oscillator, counter, voltage regulator, timer, and memory and replaces discrete component-based circuits.
How do switches work
(To turn of and turn on)
Why do we use diodes in a circuit?
The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction), while blocking it in the opposite direction (the reverse direction).
What is Zener diode also used for?
Voltage Regulator
What does a capacitor do to power?
A capacitor is a device that stores energy within an electric field.
How integrated circuits are made?
electronic circuits with components such as transistors are formed on the surface of a silicon crystal wafer.
What are the 3 most common switches used?
the Single Pole Switch, the Double Pole Switch, and the Three-Way Switch.
Where are diodes used in everyday life?
LEDs are used in sensors, lightning devices, and many more electronic devices. Zener diodes are used for the regulation of voltage.
How does Zener diode regulate voltage?
The Zener diode is often in use as a voltage regulator, primarily because the voltage drop across the diode is constant.
What does a capacitor do when it goes bad?
whatever motor it's attached to can get overheated and burn out.
What are integrated circuits made of?
Integrated circuits are compact electronic chips made up of interconnected components that include resistors, transistors, and capacitors.
What is the function of switches?
The function of switch in an electric circuit is to either make or break the electric circuit
How do you know if a diode is on or off?
If the voltage across a diode is negative, no current can flow*, and the ideal diode looks like an open circuit
What is the difference between a Zener diode and a normal diode?
a diode is a semiconductor that conducts in a single direction only, whereas a zener diode conducts in both forward and reverse biased directions.
Does adding a capacitor change real power?
the reactive power coming through supply lines is reduced and supply current pf improves.
What metal is integrated circuits?
silicon, germanium, or gallium arsenide,
What are the 4 types of switches?
single pole single throw, single pole double throw, double pole single throw, or double pole double throw.
At what voltage does a diode turn on?
0.7 volts.
Which devices use Zener diode?
These kinds of circuits are generally used in TV and FM transmitters to remove interference.
Can a motor run without a capacitor?
Induction motors are the ones usually requiring starter capacitors and the 3-phase versions of them don't require capacitors being inherently self starting.
What is an example of an integrated circuit?
Microcontrollers, microprocessors, and FPGAs, all packing thousands, millions, even billions of transistors into a tiny chip, are all integrated circuits.
