Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
How do power cords differ?
Power cords have different voltage rate, example 7A/125V cord can hold much voltage than 3A/125V. The higher the current flow can melt the lower type of power cord that is dangerous and can cause fire. Base on my knowledge there are different types of power cords according to the ampere and voltage needed.
Why do the reading differ for increasing and decreasing values of the lamp voltages?
at the time of decreasing lamp voltage as the temperature is already high the gas in the lamp is already in ionized state leading to different resistance ,but when increasing voltage the gas is not in ionized state it ready to ionize ,so there is slightly variation in resistance . :)
Why does the no-load characteristic differ for increasing and decreasing excitation current?
No-load characteristic knows as magnetic characteristic or open circuit Characteristic (O.C.C). It shows the relation between the no-load generated e.m.f in armature, E and the field or exciting current Im at a given fixed speed. The excitation voltage is directly proportional with excitation current. When excitation voltages increase so do excitation currents also increase.
What is the percentage voltage drop for feeders?
In the CEC (Canadian Electrical Code) voltage drop for feeders is stated in rule 8-102. Voltage drop in an installation shall not exceed 3% in a feeder or branch circuit. This percentage may differ in the NEC (National Electrical Code).
What will the current be on a hand held meter on a three phase motor if you clamp to two leads?
No way to tell. first off odds are you're measuring voltage rather than current, but apart from that the value would differ with your grid service and the rating of the motor
How does power amplifier differ from a conventional voltage amplifier?
A voltage amplifier does not have to supply significant current bur a power amplifier does.
Why in a circuit using power I equals Watts divided by Volts when you increase voltage the current will reduce so why does this differ from Ohms law when you increase voltage the current increases?
When you increase voltage (V) then, to get the same total power (W), the current (I) must be decreased. This result comes from the Power Law: Power = voltage x current Ohms Law does not deal with power at all, it deals only with the relationship between voltage, resistance and current: Voltage = resistance x current
What happens to voltages and currents when there are passive elements connected in series and in parallel?
In a series circuit the current flow in each element is equal but voltage across the each element is differ. In a parallel circuit the voltage across the each element is equal but current flow in each element is differ.
Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
In a series circuit how does the current differ at different places along that circuit?
In a series circuit, current will remain the same through all elements, and the voltage drop across elements will vary. So the answer is: it doesn't.
How is Mexico's education differ from the US?
different measuring
Why is the peak voltage not exactly equal to the peak voltage of the alernating voltage and by how much it differ?
If you are referring to the voltage after the rectifiers in a powersupply, it is due to the voltage drop across the rectifiers.
Why parallel connection is most commonly used in your home?
In parallel connections voltage will be same in all paths, only current will differ. That's why its widely used in home connections
What is electrical checks?
The term electrical checks will differ with respect to the machine or system being referenced. Electrical checks on a car will include the DC battery Voltage, charging voltage and current and may be voltage during engine starting. On a machine it could be main voltage secondary control voltages and even specific test point voltages on a control board.
How did Renaissance art differ from earlier periods in terms of painting technique?
Renaissance art differ from earlier periods in terms of painting technique Renaissance artists used oil paints on dry walls.
Can a 30 Amp 125 V plug be replaced with a 250 V plug?
In North America the answer would be no. The pin configurations for voltage and amperage all differ. This is so that an under voltage or under current device can not be used on higher amperage's and voltages.See related links below.
