What are applications of OHM METER?
It measures resistance in a component or circuit to determine if there is a break in that circuit or component. If there's no resistance, it means there's a break, as no electrical current is passing through.
What are the approximations of open circuit and short circuit tests?
Firstly turn of the power before this test...Using a resistance or continuity tester you should get the following results:Short circuit: Very low resistance (nearly 0 ohms) or the bell will ring.Open circuit: Very high resistance (Somewhere in the range of Mega ohms) or the bell will not ring.The reason for this is because and open circuit has a gap in it (which has high resistance).The short circuit has wires that are crossed and so has a really low resistance.
What is the meaning of resistor?
Resistors are one of the three basic electronic components. They restrict the flow of current in an electrical circuit. Fixed resistors have a fixed value of resistance, and are used in almost every electronic circuit for lots of different reasons.
Why isn't resistance constant?
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
Why you use resistor in amplifier circuit?
Resistors come under passive electronic components and are extensively used in electronic circuits. So important are these components that it may be virtually impossible to build an amplifier circuit without involving resistors. Basically the function of a resistor is always to oppose the flow of current through it and the strength of this opposition is termed as its resistance.
What is the difference between continuity and resistance check?
Continuity is checking for a completed circuit including a short circuit. Checking resistance would be checking in ohms resistance of a circuit, motor windings or an open circuit.
Why one of the leads of resistor connected in electronic circuit is opened while measuring its resistance?
You open one of the leads of resistor connected in electronic circuit while measuring its resistance in order to not introduce error cause by other components in the circuit.
What are the components of electrical circuit?
write 3 components of an electronic circuit
What are the components of an electrical circuit?
write 3 components of an electronic circuit

What An electronic circuit is?
An electronic circuit is a network of interconnected electronic components composed of one or more loops coupled that is designed to perform some useful function. The major difference between an electronic circuit and an electrical circuit is that the electronic circuit contains active components that can amplify and/or switch signals and/or nonlinear components that modify signal shapes, while electrical circuits contain only passive linear components in most cases.

How do you test electronic circuit board components?
By using a multimeter
Which common electronic components is not found in an integrated circuit?
Inductors
How do you test electronic components?
You test electronic components in calibrate laboratorys! Answer: You put them in a circuit and measure whether their response matches their specifications.
