[ AEEL1101 ] Capacitors and Inductors

True

[ TRUE OR FALSE ] In a series capacitative circuit, the smallest capacitor has the largest voltage drop.

True

[ TRUE OR FALSE ] Capacitors store energy for use in the circuit.

True

[ TRUE OR FALSE ] Ideal capacitors do not dissipate energy; they store it for use in the circuit.

True

[ TRUE OR FALSE ] Capacitance is the measure of a capacitor’s ability to store an electrical charge.

True

[ TRUE OR FALSE ] The total capacitance of capacitors connected in parallel equals the sum of the individual capacitances.

Air Core Inductors

Cores made of plastic, cardboard, and other non-magnetic materials are classified with

True

[ TRUE OR FALSE ] Inductance is directly proportional to the area of the magnetic core and inversely proportional to the core length.

False

[ TRUE OR FALSE ] The total inductance of several coils in parallel equals the sum of the individual inductances.

False

[ TRUE OR FALSE ] The quicker the change in current through the coil, the smaller the inducted voltage.

True

[ TRUE OR FALSE ] Ideal inductors do not dissipate energy; they store energy in the form of a magnetic field.

True

[ TRUE OR FALSE ] The unit of inductance is the henry.

False

[ TRUE OR FALSE ] The total inductance of several coils in parallel equals the sum of the individual inductances.

True

[ TRUE OR FALSE ] Inductance is the opposition to any change in current.

True

[ TRUE OR FALSE ] Inductance is directly proportional to the area of the magnetic core and inversely proportional to the core length.

False

[ TRUE OR FALSE ] An ideal inductor looks like an open circuit to dc current once the magnetic field has reached its final value.

False

[ TRUE OR FALSE ] The total capacitance of several capacitors connected in series equals the sum of individual capacitances.

False

[ TRUE OR FALSE ] Increasing the distance between the plates of a capacitor increases the capacitance.

False

[ TRUE OR FALSE ] The ideal capacitor completely dissipates all energy supplied to it.

True

[ TRUE OR FALSE ] Capacitance is the measure of a capacitor’s ability to store an electrical charge.
