Chapter 12 Series Circuits

___ is the ability to store energy in the form of an electrical charge.

Capacitance

A photocell is a voltage source that converts light energy to electrical energy.

False

In a series circuit, the higher the load's resistance or applied voltage, the less power produced.

False

The lower the power rating of a load, the lower the resistance value.

False

___ is the property of an electric device that opposes a change in current due to its ability to store electrical energy in a magnetic field.

Inductance

___ is the positive or negative state of an object.

Polarity

___ is the opposition to current flow.

Resistance

A capacitor consists of two metal plates (conductors) separated by a dielectric (insulating material).

True

A series connection is a connection that has two or more components connected so there is only one path for current flow.

True

In a DC series circuit, each component (switch, load, fuse, etc.) has a positive polarity side and a negative polarity side.

True

The current in a circuit containing series-connected loads is the same throughout the circuit.

True

The voltage applied across loads connected in series is divided across the loads.

True

A(n) ___ core inductor consists of a coil of wire wrapped around a hollow core.

air

A(n) ___ is a DC voltage source that converts chemical energy to electrical energy.

battery

A(n) ___ is an electric device designed to store electrical energy by means of an electrostatic field.

capacitor

A(n) ___ is a unit that produces electricity at a fixed voltage and current level.

cell

The unit used to measure capacitance is the ___.

farad (F)

A(n) ___ core inductor consists of a coil wire wrapped around a ceramic material.

ferrite

A(n) ___ core inductor consists of a wire of wire wrapped around a laminated steel core.
