What is the relationship between the measure of an angle and the reflex measure of the angle?
they both measure the angle in degrees
Measure of each angle of a hexagon?
each measure of the angle at point h has a measure of
The angle of rotation is the measure of the angle formed by the lines?
the answer is twice. the angle of rotation is twice the measure
What is a measure of an right angle?
The measure of a right angle is 90 degrees .
What instrument is used to measure on angle?
A protractor can be used to measure an angle.
Which is preferred for measuring emf of a cell avoltmeter or potentiometer?
A voltmeter is used to measure voltage. A potentiometer is used to vary the amount of resistance in a circuit - it has nothing to do with measuring.
What is the wiper contact of linear potentiometer represent?
The wiper sets the effective resistance of the potentiometer.
The potentiometer is which type of tranducer?
The potentiometer is a position tranducer. It forms a resistance divider, proportional to position.
Main difference between rotary and linear potentiometer?
A rotary potentiometer is designed to measure rotational movement, providing a variable resistance output based on the position of a rotating shaft. On the other hand, a linear potentiometer measures linear movement, offering a variable resistance output based on the linear position of the sliding wiper along a straight track.
What is linear Potentiometer?
A linear potentiometer is a potentiometer that changes linearly with rotation of the knob. A 30% degree turn will change the resistance 30%. It's a direct relationship. This is in contrast to log potentiometers, which change resistance logarithmically with turns in the knob.
What type of system does potentiometer belong to?
Variable resistance.
What does a variable risistor do?
It is a resistor which resistance is changeable, such as a potentiometer.
Applications of Carey foster's bridge?
The Carey Foster bridge works on the principle of the wheatstone bridge (potentiometer)which can be used to measure fractional resistance.
Why is copper wire not used in potentiometer?
Copper wire is not used in potentiometers because copper is highly conductive and would not provide enough resistance for the potentiometer to function properly. Instead, materials with higher resistance, such as nichrome or a graphite-based material, are used to create the variable resistance needed in a potentiometer.
What are rotatable sliding contact of rotary potentiometer and the wiper contact of liner potentiometer represent?
it represent the resistance where it can be increased or decreased
What are the limitations of the potentiometer?
A potentiometer is limited by it value(resistance) , it's wattage ( heat dissipation factor) and it's physical size.
What can one measure with potentiometers?
A potentiometer measures the potential voltage in a circuit. There are several types of potentiometers including constant current, constant resistance, microvolt, and thermocouple.
