Each parallel path in a circuit is called a ____________.
|
|
|
2.

If there is more than one path (branch) between two points, and if the voltage
between those two points also appears across each of thoe branches, then there is a __________
circuite between those two points.
|
|
|
3.
|
When resistors are connected in parallel, the current has more than one
______.
|
|
|
4.
|
The total resistance for two resistors in parallel is equal to the product of
the two resistors divided by the _______ of the two resistors.
|
|
|
5.
|
One advantage of a parallel circuit over a series circuit is that when one
branch opens, the other branches are not __________.
|
|
|
6.
|
Another common use of parallel circuits is in ___________ electrical
systems.
|
|
|
7.
|
All the lights and appliances in a home are wired in ________.
|
|
|
8.
|
Many control systems use parallel circuits or equivalent circuits for control
and monitoring an industrial process such as a __________ line.
|
|
|
9.
|
Parallel control circuits use _______ diagrams but add additional control
elements (switches, relays, timers and more).
|
|
|
10.
|
The result of adding the control elements creates a logical diagram, which is
referred to as ___________ logic.
|
|
|
11.
|
The voltage across any given branch of a parallel circuit is ________ to the
voltage across each of the other branches in parallel.
|
|
|
12.
|
The algebraic sum of all the currents entering and leaving a ________ is equal
to zero.
|
|
|
13.
|
A parallel circuit acts as a _________ divider because the current entering the
junction of parallel branches “divides” ip into several individual branch
circuits.
|
|
|
14.
|
The total current divides among parallel resistors into currents with values
inversely proportional to the ___________ values.
|
|
|
15.
|
Total power in a parallel circuit is found by adding up the powers of all the
_________ resistors, the same as for series circuits.
|
|
|
16.
|
When an open occurs in a parallel branch, the total resistance __________, the
total current decreases, and the same current continues through each of the remaining parallel
paths.
|
|
|
17.
|
When a parallel resistor opens,  is ________ less than its
normal value.
|
|
|
18.
|
When a branch in a parallel circuit shorts, the current _________ to an
excessive value, usually causing the resistor to burn open or a fuse or circuit breaker to
blow.
