What else can I help you with?
Why you are calculating average and rms values for ac supply?
We will always calculate rms value only since the average value of ac current or voltage is zero. So we are using rms values in the ac circuit to calculate the power and to solve an ac circuit.
When an AC 5A and dc Current of 5A applied simultaneously to the circuit then what it happen?
A DC ammeter will read zero
Should AC circuits go to or from positive battery terminal?
You would never connect any part of an AC circuit to a battery.
What is meant by wattless current?
Current flowing through an ac circuit in which power consumed is zero is called wattless current.
What happens if you use an ac circuit breaker instead of dc breaker?
A circuit breaker is easier to design for ac than dc because alternating current (ac) naturally goes to zero 100 or 120 times per second and this helps to extinguish any arc. Therefore an ac circuit breaker would not be suitable for dc assuming the same voltage and current ratings.
Can you bypass the ac pressure switch?
Yes, for charging and diagnostic testing. Never for normal operation, it is a safety circuit.
What will b the power factor of a series circut when r is made zero?
The power factor never depends on the resistance of a circuit. It depends on the equivalent inductance and capacitance in the circuit, and on the frequency of the power supply, even if the resistance is zero.
Why should current be reversed in an AC circuit?
The current in any AC circuit reverses every cycle.
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
If AC is replaced by DC in a fluorescent lamp circuit will the circuit work?
No.
When does power consumed in an ac circuit becomes zero?
'Power' is not 'consumed'; it is simply a 'rate' -the rate at which 'energy' is being consumed.No energy is being consumed by a load which is either purely inductive or purely capacitive so, for such loads, the rate of energy consumption, or the power, would be theoretically be zero. However, purely inductive or capacitive circuits only exist in theory, and all circuits exhibit some degree of resistance, so you will never have a condition under which the power of an a.c. circuits truly becomes zero.
