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.
