What is the purpose of the ground symbol used in electrical circuit diagrams?
A ground symbol (IEC symbol 5017) identifies a ground terminal. It can be used for a zero potential reference point from where current is measured. It is also for electrical shock protection.
Which of the following are commonly used as rectifiers in electrical circuits 1 anodes 2 cathodes 3 diodes?
|the opposition offered by a coil to the flow of alternating current is call||inductive reactance|
|which of the following are commonly used as a rectifiers in electrical circuits 1 anodes 2 cathodes 3 diodes||3|
|what unit is used to express electrical power||watt|
Which of the following logic gates will provide an active high out only when all inputs are different?
Which of the following logic gates will provide an active high out only when all inputs are different? XOR. The output of the XOR (Exclusive OR) gate will only be at an active high when one and only one of the two inputs is high.
Are ground and negative the same?
Ground is simply referring to a common reference charge level across the circuit. It is often most negative than the other charge levels and therefore often connected to the negative terminal of a battery, but it doesn’t have to be this way.
What is the symbol of ground?
Most of the time the ground symbol you are most familiar with, the 3 decreasing-length lines, is the one that is used in a generic sense to illustrate ground. The three diagonal lines and the decreasing horizontal bars represent chassis and earth ground, respectively.
Which diode is used in Rectifier?
They are also used elsewhere in circuits where a large current must pass through the diode. All rectifier diodes are made from silicon and therefore have a forward voltage drop of 0.7V.
Rectifier diodes (large current)
|Diode||Maximum Current||Maximum Reverse Voltage|
What is peak inverse voltage?
Peak Inverse Voltage (PIV) or Peak Reverse Voltage (PRV) refer to the maximum voltage a diode or other device can withstand in the reverse-biased direction before breakdown. Also may be called Reverse Breakdown Voltage.
What are 3 basic features of an electric circuit?
Every circuit is comprised of three major components:
- a conductive “path,” such as wire, or printed etches on a circuit board;
- a “source” of electrical power, such as a battery or household wall outlet, and,
- a “load” that needs electrical power to operate, such as a lamp.
What are the 4 main components of an electrical circuit?
The essential elements in a basic electrical circuit consist of: A source, load, and ground. Electricity cannot flow without a power source (battery), and a load (bulb or resistor-electrical device/ component) and a closed conductive path (wires connecting it).
What are the two requirements for an electric circuit?
To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.
