How does the resonant frequency affect the voltage drop across a resistor?

How does the resonant frequency affect the voltage drop across a resistor? For all intents and purposes, a resistor has no resonance frequency. its parasitic capacity is considered insignificant. if…

Why is possible to change instantaneously voltage across a resistor?

Why is possible to change instantaneously voltage across a resistor? The capacitor and inductor do not allow sudden changes in voltage or current. This is because both devices build up…

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

What is the difference between a fixed resistor and variable resistor? Variable resistors means that a resistor can change its resistance value through the control of a person or himself.…

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

What is the difference between a non inductive and inductive resistor? Inductive Resistor: Any circuit in which a change in the current is accompanied by a change in the flow…

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

Will using a non resistor spark plug increase or decrease engine power? Using a non-resistance spark plug in a resistance plug system weakens the spark and therefore affects engine performance.…

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

Why do we use wire wound resistors in electronic applications? Wire wound resistance potentiometers can be manufactured to provide both high power and high precision. These potentiometers are often used…

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? The resistances assure this moderation; they act as dams that control the flow of current…

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…

What is the meaning of the tolerance of a resistor

What is the meaning of the tolerance of a resistor? Common are 5% and 1%. Sometimes they are marked with an extra color band indicating tolerance. The tolerance is the…

How do we calculate heat produced in a resistor

How do we calculate heat produced in a resistor? The voltage squared (in volts) divided by the resistance (in ohms) is equal to the power (in watts). take the voltage…

Why do capacitors need a resistor to discharge

Why do capacitors need a resistor to discharge? A charged capacitor contains a certain amount of potential energy. The inclusion of a resistor on the discharge circuit involves a potentially…

Why is a resistor used as a load in rectifier

Why is a resistor used as a load in rectifier? A rectifier suggests that you are referring to a power supply, and that the load would never be just a…

What can cause a resistor to become non ohmic

What can cause a resistor to become non ohmic? all resistors have a range of conditions to be ohmic. One of the most important is the temperature: heat them enough…
