How can you block ac current?
You can block AC current by using a filter with a pass-band that is outside the frequency of the AC current.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
What is the purpose of blow out coil with laminated core in ac power contactor?
The laminations reduce a core loss called Eddy Currents, which are set up in the core by the ever changing AC current.
What current flows in one direction then the opposite direction?
AC, Alternating Current.
What is the sign for ac and DC current?
AC means alternating current DC means direct current there is no polarity reversal
What is perhaps the single most important advantage of using AC compared to dc current?
AC current can be transmitted with less loss
Formula for power loss in ac cables?
P = I2R Where: P = power loss I = current R = resistance
Does a fan run on a dc current or ac current?
AC
How can you block ac current?
You can block AC current by using a filter with a pass-band that is outside the frequency of the AC current.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
Did ceiling fan operate on dc or ac current?
ac current
What current is produced in ocean thermal energy conversion dc current or ac current?
ac
Why is it incorrect to say AC current?
ac stands for alternating current so ac current means alterneting current current. its like entering your pin number on an ATM machine.
What is the purpose of blow out coil with laminated core in ac power contactor?
The laminations reduce a core loss called Eddy Currents, which are set up in the core by the ever changing AC current.
What form of electricity comes out of a Wave Generator?
It depends on how the generator is set up. Some will produce DC (Direct Current) and others will produce AC (Alternating Current). Where possible AC electricity will be produced as it runs through the grid without much loss of power.
What current flows in one direction then the opposite direction?
AC, Alternating Current.
What is the sign for ac and DC current?
AC means alternating current DC means direct current there is no polarity reversal
