Resistance is characterized by the opposition to the flow of electric current, measured in ohms. It depends on the material's properties, such as temperature, length, and cross-sectional area. In a broader context, resistance can also refer to the ability to withstand change or pressure, manifesting in social, political, or psychological contexts. Overall, it signifies a force that impedes progress or movement in various systems.

Which of the material is used for the swamping resistance that is connected in series with the working coil of a voltmeter?
A swamping resistor is usually manufactured from the metal alloy manganin (trade name), or other alloy with similar resistance/temperature characteristics -i.e. practically zero temperature coefficient of resistance. In other words, its resistance will remain more-or-less constant over a wide range of temperature variation.
What is the relative resistance of a good ammeter and a good voltmeter?
A good ammeter has low resistance to ensure it does not significantly affect the current flowing through the circuit it is measuring. In contrast, a good voltmeter has high resistance to minimize the current drawn from the circuit, allowing it to measure the voltage across a component without altering its behavior. This difference in resistance characteristics is crucial for accurate measurements in electrical circuits.

What are the characteristics of a common emitter amplifier?
There are a number of characteristics found in a common emitter amplifier. Not only are the parameters considered, but also their performance. Characteristics and performance are: voltage gain/ medium; current gain/ medium; power gain/ high; input / output phase relationship/ 180 degrees; input resistance/ medium; and output resistance/ medium.
What is the resistance of a 36watts ballast?
The resistance of a ballast can vary depending on its design and specific characteristics. To calculate the resistance of a 36-watt ballast, you would first need to know the voltage it operates at. Using Ohm's Law (R = V^2 / P), where R is resistance, V is voltage, and P is power, you can determine the resistance.
What is base resistance Rb?
Base resistance (Rb) is the resistance seen by the base terminal of a transistor when analyzing its behavior in a circuit. It is a parameter used to model the input impedance of the transistor and is crucial in determining the biasing and signal amplification characteristics of the transistor circuit.
