What are the main difference while applying kirchoffs laws to dc circuits and ac circuits using meter readings?
For DC circuits, an alebraic sum is required. For AC circuits, a phasor sum is required.
What statements is not true for AC?
Ohm's law does not apply to AC circuits.
What is the use of capacitor in dc circuits?
It will minimize curent flutuations, it olso helps in AC circuits( in AC I tink it absorbs frequenci emmisions).
What does ac stand for in circuits?
alternating current
How you can calculate ampere?
Voltage (volts) divided by Resistance (ohms). For AC circuits the resistance part of this formula is replaced by "impedance" which involves the effects of capacitors and inductors as well.
Can resistors function the same in AC circuits as in DC circuits?
Yes, they both can add a load to a circuit.
Transformer are used in circuits containing both dc and ac?
No transformers only work with AC.
Does meter loading in ac circuits depend on frequency?
yes
To which circuits superposition theorem can be applied?
both ac and dc
How do you calculate 3ph AC motor power?
How do you calculate 3ph AC motor power?
What type of capacitor is often used in power-supply circuits to filter the rectified AC?
The electrolytic capacitor is most often used in power supply circuits to filter the rectified AC.
Can i have a view of the power circuit of an AC generator?
please how can i diagnose faults on an AC generator power circuits?
