200. assignment (rlc short answers)
Please explain why these are true/false or always true/false:
[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 the 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.
