Why can the resistance of a resistor be measured while it is in a circuit?

Why can the resistance of a resistor be measured while it is in a circuit? Normally, it cannot be. In simple terms, you will also measure the other components of…

Why do we use a resistor to dissipate energy if it is an economical loss?

Why do we use a resistor to dissipate energy if it is an economical loss? a phisophical response to your question would be that everything is good in moderation. the…

Could a wire wound adjustable resistor be used as an electrical ballast?

Could a wire wound adjustable resistor be used as an electrical ballast? Without specifying what you mean by ballast, it is impossible to give a meaningful . what do you…

Will using a non resistor spark plug increase or decrease engine power?

Will using a non resistor spark plug increase or decrease engine power? ni. This is one of the lies on which the aftermarket ignition companies and gasoline candle companies depend…

What is the difference between a non inductive and inductive resistor?

What is the difference between a non inductive and inductive resistor? some resistors are wired around a core (non-magnetic) and others are wound up and returned for the same number…

What is the difference between a fixed resistor and variable resistor?

What is the difference between a fixed resistor and variable resistor? in the resistance, we can not change the resistance value of its constant, variable resistance, we can change the…

What is the difference between a transistor and a variable resistor?

What is the difference between a transistor and a variable resistor? any resistance is a linear device, a transistor is nonlinear. a linear device has a linear relationship between voltage…

Why is possible to change instantaneously voltage across a resistor?

Why is possible to change instantaneously voltage across a resistor? nonlinear resistance – eg a transfer resistor – yes, a transistor. you can modulate its column resistance by changing its…

Why do capacitors and inductors store energy but resistors do not?

Why do capacitors and inductors store energy but resistors do not? a capacitor stores the electrons as a static charge, an inductor in the form of a magnetic field. a…

Why the voltmeter needs to be connected in parallel with resistor?

Why the voltmeter needs to be connected in parallel with resistor? A voltimeter must measure the voltage on a component / device, this can only be done if you connect…

When does the open resistor read an infinite value in an ohmmeter?

When does the open resistor read an infinite value in an ohmmeter? If the resistor is really open, it will measure infinity when you check it with an ohmmeter. in…

What is the difference between resistor capacitor and inductor?

What is the difference between resistor capacitor and inductor? Resistances dissipate energy in the form of heat, capacitors store energy in an electric field, and inductors store energy in a…

Would using a resistor in a circuit make a battery last longer?

Would using a resistor in a circuit make a battery last longer? Well, just adding resistance to part of a circuit does not guarantee that the current will drop. it…
