When was Voltage AC created?
Voltage AC was created on 2004-12-14.
Who to increase torque of ac motors?
ac voltage
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
Can you connect an AC source in series to DC source - then what happens to the current under a steady state condition?
With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.
Constant voltage power supplies will maintain a constant voltage under varying?
current.
Why can not store ac in battery?
Batteries are storing charge or free electrons. The state is by nature a fixed voltage rather than a varying voltage. You can convert the battery charge to AC by using what is called an inverter.
Is it appropriate to use dc supply in a transformer?
Not usually. Transformers require a varying magnetic field, which is induced by AC voltage.
Is voltage in a home about 70 percent of the peak voltage that is generated?
A modern power grid consists of many voltages and currents, all being interconnected by transformers, which trade off voltage and current. A typical power generator usually generates electricity at a few thousand volts AC, which is then stepped up to around 120kv for distribution, then stepped down to around 30kv, for secondary distribution, then finally down to 240v/120v for domestic use. Engineers typically measure the voltage of AC circuits using "RMS voltages" (Root Mean Squared voltages) This convention is used because of the varying nature of AC, and relates the varying AC voltage to an effective DC voltage. RMS Voltage for typical AC =Peak voltage / Square root(2) which is approximately equal to peak voltage* 70%
ABS sensor produce AC voltage or DC voltage?
AC !
How can the frequency and voltage of an alternator be changed?
The frequency is changed by varying its speed, and the the voltage is changed by varying its field current.
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
When was Voltage AC created?
Voltage AC was created on 2004-12-14.
What is the voltage for a printer?
Most of the printers offered in the USA have a voltage of 110V AC input and 8V AC output, whereas the printers offered in the Europe have input voltage of 220V AC and output voltage of 8V AC.
Is tranformer used to increase or decrease AC voltage?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
What is the difference between Variable Speed Drive and Variable Frequency Drive?
A variable frequency drive (VFD) refers to AC drives only and a variable speed drive (VSD) refers to either AC Drives or DC Drives. VFD's vary the speed of an AC motor by varying the frequency to the motor. VSD's referring to DC motors vary the speed by varying the voltage to the motor.
How does capacitor discharge while ac supply is on?
For part of the AC voltage wave, the capacitor will be above the source voltage, and will discharge until the AC voltage wave increases above the capacitor's stored voltage.
What is the function of step-down transformers?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of Transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
