Q

How do you calculate current (I) in a parallel circuit?

A

1) add the reciprocals of each individual resistors resistance to find Req (the reciprocal of the total reistance)
2) divide the voltage by the Req to find current

22
Q

In a parallel circuit the _______ ____ is the same across each resistor.

A

Voltage drop

23
Q

In a series circuit what is the equation to find Rt?

A

R1 + R2 + … = Rt

24
Q

In a parallel circuit what is the equation to find Rt?

A

1/R1 + 1/R2 + … = 1/Rt
OR
Rt = (R1 * R2)/(R1 + R2)

25

30
Q

A u-tube water manometer measures ___ _______ in units of __ of ____ (_____) directly from the ______ on the device

A

Air pressure; cm of water (cmH20); gauges

31

A

Can’t use during speech/not useful for pressure measures during speech

33
Q

A pneumotachograph works by using a ____ or ___ inserted in the _____ delivered to a ____ which contains a screen which provides a known ______ and pressure drop across the screen is measured by a _________ _______ _______.

A

Mask or tube; nostril; tube; resistance; differential pressure transducer

34
Q

Air flow can be calculated by this equation:

A

V = change in P / R

35
Q

A body plethysmograph can be used to measure _______ changes during _____

A

Volume; speech

36
Q

In a body plethysmograph the subject is seating within a ______ ___ and any changes in _____ or _______ volumes are reflected in the volume changes _______ the ___

A

Sealed box; thoracic or abdominal; within the box

37
Q

A body plethysmograph can be attached to a _________ for _____ output

A

Transducer; graphic

38
Q

What is an advantage of a body plethysmograph?

A

Can be used during speech

39
Q

What is a disadvantage of a body plethysmograph?

A

Large, expensive, awkward

40
Q

How does a body plethysmograph work?

A

When someone breather in, their lung volume increases, so chamber volume fear eases and chamber pressure increases
