@An oscilloscope trace can be pulled left or right by applying a p.d to:
X-plates
Y-plates
Grid

@Electrons are emitted by:
Cathode
Anode
X-plates

@Which one of the following statements about electrons is correct?
They are deflected in a magnetic field
They are only deflected in North-South
They are not deflected by magnetic fields

@Which one of the following statements about electrons is correct?
They have a negative charge
They have no charge
They have a small positive charge

@An oscilloscope trace can be deflected up or down by applying a p.d trace to:
Y-plates
X-plates
Cathode

@Another name for beams of electrons is:
Cathode rays
Microwaves
X-rays

@The oscilloscope control that causes the trace to move from left to right is:
Time base
X-gain
Trigger

@In an oscilloscope, electrons are attracted towards:
Anode
Cathode
Filament

@If an alternating voltage is applied to the Y-plates of an oscilloscope then the trace will:
Oscillate up and down
Do nothing
Move upwards

@The diagram shows the trace on an oscilloscope. The time base was:
#scope1
turned on
turned off
doesn't make any difference whether its turned on or off

@For an oscilloscope to produce this kind of trace it must have been connected to:
#scope1
an a.c source
a d.c source
a 1.5V cell

@The diagram shows the trace obtained on an oscilloscope. By studying the settings on the oscilloscope you can calculate:
#scope1
the source voltage (p.d)
the source current
the source resistance

@An experiment is set up, and produces this trace on an oscilloscope. Making the time base faster will:
#scope1
show more waves on the screen
will make the waves taller in height
make the waves smaller in height

@An experiment produces an a.c output, measured on an oscilloscope. The root-mean-square (rms), or effective value, is:
#scope1
slightly less then the amplitude of the trace shown
exactly the same value as the amplitude of the wave
dependent on the number of waves shown on the screen

@A source is connected to an oscilloscope, and produces the trace shown. The source is definitely not:
#scope1
a 1.5V cell (battery)
mains electricity
the output from a dynamo
