What else can I help you with?
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
When an AC 5A and dc Current of 5A applied simultaneously to the circuit then what it happen?
A DC ammeter will read zero
What is ac resistance of a diode?
ratio of ac voltage applied across the diode to the ac current flowing through it
What happen when 220v dc is applied to a 220v ac single phase transformer?
The current would rise until it blows the fuse or breaker and that would produce an arc as the transformer's inductance tries to maintain the current.
Can ac pass through capacitor?
AC can pass through a capacitor. The higher the frequency of AC the lower the reactance (like resistance). The current and applied voltage are 90 degrees out of phase the current leading the voltage by this amount.
What happen when ac current passes through resistor?
it resists the flow of cuurent
Can you give any practical prove of difference between the ac and dc?
if ac changes direction then how current happen to flow
If DC is applied to the primary of a transformer is there any current in the secondary and if there is then whether ac or DC?
first, understand that a transformer is an AC DEVICE. it wont work on dc...
Does a television run on alternating current?
The television runs on Direct current or DC. Though AC is applied, it is converted to DC and used by the television to operate.
Why does a ac voltage applied across a load resistance produce alternating current in the circuit?
Because V = I x R or Voltage = Current x Resistance. Since resistance is linear there is a linear relationship between Current and voltage. If you have DC voltage you have DC current and if you have AC Voltage you have AC current. Note that there is a linguistic recognition of this relationship in that the voltage is described in terms of the current.
When the ac is applied to relay what happened?
When current is applied to the windings of the relay, a magnetic field is created, and this will attract the moving part of the relay, which in turn may open or close other electrical contacts. A relay may be operated by either ac or dc according to its design.
When you stepup ac voltage the current drops.What will happen with CURRENT if DC is stepped up?
WHEN YOU STEP UP THE VOLTAGE AND THE LOAD IS THE SAME MORE CURRENT WILL FLOW NOT LESS. AND THAT WILL HOLD TRUE FOR DC AS WELL. IF THE LOAD REMAINS THE SAME AND YOU INCREASE THE CURRENT AC OR DC THE VOLTAGE WILL INCREASE
