∙ 13y ago
'Polarity' as it applies to currents and potential differences in a circuit refers to the directions in which these quantities act. It becomes important if, for example, you are using Kirchhoff's Laws to solve a complex circuit.

What is a 1k resistor?
It is a passive electrical device with a resistive value of 1000 ohms, used for limiting current or dropping voltage.
What is the purpose of a variable?
A variable resistor is used in cicuits to vary the current passing through the resistor. It is commonly used to change the value of current across a circuit, or to act as a voltage divider. They are commonly equiped with a knob outside of a cabinet, to enable the user to adjust the operation of a circuit, like a volume control on a radio or amplifier.
What are the significance of modulus of elasticity and modulus of rigidity in machine design?
IN MACHINE design modulus of elasticity place an important role. from the value of modolus of elasticity we come to know about maximum value of load that can be to the given material upto which the material is assume to follow the hook's law.
What is difference between null value and not null value?
Putting it very simply a null value is empty and a not null value contains something.
How do you covert watts to amps?
Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples. 2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps 2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps 100 watt car amplifier current = 100 divided by 12 volts = 8.5amps

An AC has a peak value of 12 amps what is the average value of the current?
i think average value of current in ac current is zero.
What does current value mean?
Either the actual value of something, or the value of a current. It really depends on the context.
2 What is recording instrument?
A recording instrument is that which performs two functions simultaneously-viz., indicating and recording. The measured value will be indicated by the pointer and at the same time it records the reading on a graph or paper.
What is the current market value of siver by the ounce?
“What is the current market value of siver by the ounce”
When is it advantageous to record a decimal?
If recording decimal value of X. When you wish to have an accurate record of the numeric value of X.
What is single polarity and double polarity of pulse amplitude modulation?
SINGLE POLARITY: In single polarity PAM the height of the pulse is made larger than the maximum negetive value of the signla so that it remains positive even when the input is negetive DOUBLE POLATRITY: In double polarity PAM the pulse height is made proportional to the amplitude of the signal at the instant of the sampling P.Nagarjuna B-tech 3rd year, ECE, Sri Indu college of engineering and technology
What is fusing current?
The fusing current is a value of current that causes the fuse to melt and interrupt the flow of current. Usually, reference is made to the minimum fusing current which is the smallest value of current that will cause the fuse to melt.
What is the current gain value of BC 148 transistor?
The hFe (current gain) on the BC148 ranges from a minimum value of 20 to 100, depending on collector current, with a maximum value of 300.
How do you find the value of a capital stock purchased in 1981?
To obtain the current value of capital stock it should be brought to a finical advisor. The current value is based on the purchase price and the current stock value. It can change daily.
