What else can I help you with?
Why are transmission voltages in ac systems generally higher than those in dc systems?
The main advantage of using ac is that you can step up and step down the voltage by means of a transformer,since transformer works only with ac. another thing is that if dc power is used for transmission,then the power loss associated with t will demand the use of transmission lines which are very thick(have a larger cross section)..for long distance transmission this may lead to the requirement of power lines with impractical dimensions.
What does resistance in an electrical circuit mean?
i dont know really, thats why im asking right
How do you get tolerance of resistor?
That depends on how much resistance is called for through the engineering, there is tiny resistance (mf) microfared on up huge resistance seen on electrical poles. Your circuit engineering formula dictates the needed resistance or it will just burn or not flow at all, you cannot answer the question without first asking a question..How much resistance do you need. They can be produce for virtually any tolerance.
What is the equivalent resistance through the enire circuit of 90 volts?
Not enough information. In the case of simple circuits, usually you would add resistances that are in series, and use a slightly more complicated formula for resistance that are in parallel. You CANNOT determine an equivalent resistance known only the voltage. However, if you know the total current, you can divide the voltage by the total current to get the equivalent resistance.
Why multimeter cannot used for measurement of insulation resistance?
Because ordinary ohmmeters are calibrated to measure a range of resistance values that are significantly lower than the resistance of insulation. It should also be realised that we usually test insulation resistance while subjecting the insulation to a high electric field, which a normal ohmmeter is incapable of producing.
How would you connect a voltmeter?
A: It must be connected across the device ammeters cannot measure DC current directly
Contact potential cannot be measured?
A: SURE it can while open it will measure the potential when closed it will measure the small voltage drop due to the resistance if any.
Can a displacement current be measured with an ammeter expain?
Displacement current can not be measured by ammeter because it is the current which produce between the plate (space)due to change of electric flux and it is directly proportional to the rate of change of electric flux.
How resistance is intensive?
I cannot answer this question
The volume of a gas cannot be measured?
FALSE
What do you call research that cannot be measured?
unquantifiable.
What is the thing cannot be measured?
Happiness or sadness.
What are non-measurable properties?
cannot be measured
What is impedance in speakers and can it be measured in watts?
Impedance in electricity is described as an opposing force to electron flow. It consists of a combination of resistance, capacitance, and inductance. This forms the actual "resistance" to electron flow in a circuit versus "pure resistance"such as a resistor added in a circuit to slow electron flow. Impedance is more prevalent in AC circuits versus DC circuits as it reacts to AC current flow much more than DC current. Current flow in a speaker circuit is considered AC so impedance is more meaningful in a speaker setup. Impedance can be measured or calculated based upon current flow so it can be converted to watts using the formula Watts = amps times voltage.AnswerImpedance is the vector sum of resistance and reactance, and is measured in ohms. No, it cannot be measured in watts, which the unit for power.
What does immeasurable mean?
If something is 'immeasurable', it cannot be measured.
What is the verb of qualitative?
qualitative is a quality it cannot be measured
Is francium hard?
