Question

One or two sentence answers are fine. But please be clear with explanations.

For each statement, decide whether it is always true, always false or true in certain
circumstances. State which case applies to the statement, describing why you
chose the answer you did and cite an experiment or principle of Physics which
supports` your claim.
[1] In a capacitor in an AC circuit, the electric field leads the current.

[2] The impedance of a capacitor increases with frequency.

[3] In an LR circuit with a switch, the current through the inductor when hte switch has
been closed for a long time is zero.

[4] The voltage across a capacitor in a DC circuit approaches its final value exponentially.

[5] To make a high pass filter, use an RC circuit with the output voltage measured across
the capacitor.

[6] In an RC circuit, the electric and magnetic fields reach their maximum values at the
same time.

[7] In an ideal transformer (no energy loss), the side with more turns gives a higher
voltage and larger current than the side with fewer turns.

[8] The inductance of a coil depends on the number and size of the coils and the material
in the wire.

[9] The capacitance of a capacitor is decreased by placing a material with a higher
dielectric constant between the plates.

[10] Like resistors, inductors in series and capacitors in series add, while inductors and
capacitors in parallel combine as the reciprocals.

[11] Once the initial phasors for an AC circuit are plotted, they each rotate at different
rates as time progresses.

Answer 1

I have answered these question in in depth with correct reasons. I takes some time to write 4 pages, but you are getting the best answers. please rate the best amswer!

Answer 2

2)

true

The term "impedance" is a general term for any combination of resistance, capacitive reactance and inductive reactance.

With a combination of all three, as frequency increases, the impedance can go either way and even reverse direction ( up, down, up OR down, up, down)
