Description : why ohm's law is not applicable for ac circuit?
Last Answer : We can use Ohm's law for AC circuit if circuit consists of linear components and devices.
Description : 27] In a transformer, the leakage flux of each winding is proportional to the current in that winding because A. Ohm's law applies to magnetic circuits B. Leakage paths do no saturate C. the two windings are electrically isolated D. mutual flux is confined to the core
Last Answer : B. Leakage path do not saturate
Description : Does the linear circuit obey Ohm's law?
Last Answer : Yes linear circuit obey Ohm's law and nonlinear circuit not satisfied Ohm's law.
Description : Suppose the ammeter or voltmeter you are using in the Ohm’s law experiment does not have +ve and –ve terminal markings. How will you use such ammeter or voltmeter in the circuit?
Last Answer : Answer. We will use a typical battery to determine this. Connect them with wire and the battery if their readings are positive then we have connected them correctly and if their readings in negative then we have connected in opposite polarity.
Last Answer : If the resistance of a conductor does not vary in accordance with Ohm's law it is known as non-linear conductor

Last Answer : It can be applied to AC circuits
Description : Can we apply the superposition theorem to AC circuit?
Description : Can we apply Norton's theorem in an AC circuit?
Description : Pick out the correct statement. (A) A forced vortex occurs when fluid rotates as a solid about an axis (B) In laminar flow, Newton's law of viscosity does not apply (C) A free vortex occurs, when fluid rotates as a solid (D) In turbulent flow, there are neither cross-currents nor eddies
Last Answer : (A) A forced vortex occurs when fluid rotates as a solid about an axis
Description : .As a wave travels down a spring, the amplitude slowly decreases. Why does this occur? A. The law of conservation of energy does not apply to waves. B. The energy is spread out along the entire ... due to friction as the particles in the spring rub against each other. E. all of the above
Last Answer : D. Some energy is lost due to friction as the particles in the spring rub against each other.
Description : State different types of power in ac circuits. Write the expression and units for the same. Draw the power triangle.
