How much power is consumed through a 3 amp?
-- If the 3 Amp is being drawn from a battery,then the battery is supplying3 x (Voltage of the battery) watts.-- If the 3 Amp is flowing through a resistor,then the resistor is dissipating9 x (Resistance of the resistor) watts.
Why the capacitor time period formula is given as t equals RC?
-- The quantity 'RC' has the physical dimensions of Time. -- If the capacitor is charging through a resistor, then 'RC' is the time it takes to charge up to (1 - 1/e) of the voltage it still has to go to become fully-charged. -- If the capacitor is discharging through a resistor, then 'RC' is the time it takes to discharge to 1/e of its present voltage. -- ' e ' is the base of natural logarithms, approximately 2.71828... -- 'RC' is called the 'time constant' of the resistor/capacitor combination.
How would you know which resistors are in parallel with each other?
Resistors are in parallel when they are connected to the same two nodes, creating multiple paths for current to flow. You can identify them by checking if each resistor's terminals are connected to the same points in the circuit. Additionally, in a parallel configuration, the voltage across each resistor is the same, while the total current is the sum of the currents through the individual resistors. A quick visual inspection or using a multimeter to measure voltage can help confirm their arrangement.
What is x y recorder and explain its working principle advantages disadvantages and applications?
Operating Principle: In x-y recorder, an emf plotted as a function of another emf, this is done by having 1 cell balancing potentiometer controlling the position of paper provided while another cell balancing potentiometer control the position of recording pen.
Why an ideal voltimer must infinity resistor?
An ideal voltmeter must have infinite resistance to prevent it from drawing any current from the circuit it is measuring. If it had finite resistance, it would alter the voltage across the component being measured, leading to inaccurate readings. By having infinite resistance, the voltmeter ensures that it does not influence the circuit, allowing for precise voltage measurements.
What is a potentionmeter?
a potentiometer is a varible resistor use as a voltage provider.
Why is a voltmeter used rather than a potentiometer?
A potentiometer is a variable resistor, while a voltmeter is a device that measures voltage.
What do you call the variable resistor when it is set up to alter the size of the voltage over the resistor?
A potentiometer.
What is advantages and disadvantage of potentiometer?
Potentiators works well as a voltage resistor or variable resistor. It is often used for volume controls on a radio, but they can be cumbersome.
What is the name of a variable resistor with 3 terminals?
It's called a 'variable resistor'. However, it can function as a 'rheostat' (to control current) when two terminals are connected, or as a 'potentiometer' (to control voltage) when three terminals are connected. The terms, 'rheostat' and 'potentiometer' do not describe the device itself, but how it is being used.
What is linearisation of potentiometer?
Linearization of the potentiometer refers to the inclination of the three parts of a potentiometer. The parts includes a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
Why do you measure emf with a potentiometer not with voltmeter?
EMF (E''electromotive Force'') is another term for Volts, hence the E in electronic formulas and EMF is measured with a volt meter. A potentiometer is not a meter at all, it is a variable resistor
How can a potentiometer be a rheostat?
A rheostat and a potentiometer are two different applications for the same device, a variable resistor. These devices have three terminals. Two terminals are connected across the complete resistor, while the third terminal is connected to a controllable wiper. The variable resistance is provided between the wiper terminal and either one of the other two terminals.When used to control current, it is called a rheostat. When used to control voltage, it is called a potentiometer.
What is the function of rheostat in this experiment?
A rheostat is the name given to a variable resistor when it is used to control current. When a variable resistor is used to control voltage, we call it a potentiometer.A rheostat is connected in series with a load, and two of its three terminals are used. A potentiometer is connected in parallel with the supply, and each of its three terminals are used.So the terms 'rheostat' and 'potentiometer' are the names given to describe the function of a variable resistor, not the variable resistor itself.
How do you compute resistor?
The resistance in a circuit is calculated by dividing the voltage by the current (R=V/I) (Ohm's Law).
What is other name for variable ressitance?
Another name for variable resistance is potentiometer. It is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
Is a potentiometer and voltage regulator the same thing?
Ah, what a lovely question! Potentiometers and voltage regulators are similar in that they both deal with controlling voltage, but they have different functions. A potentiometer is like a knob that can adjust the voltage manually, like tuning the volume on a radio. A voltage regulator, on the other hand, automatically maintains a constant voltage output, like a guardian angel making sure everything stays just right. It's all about finding the right tool for the job, and both have their own special ways of bringing harmony to your circuits.
