Explain how you can measure the magnitude and direction of the Earth's
field using the apparatus in Experiment 1. - ✔✔Use probe to find direction
in which magnetic field is greatest, record angle using a protractor.
True or False: Electric field lines point along equipotential
surfaces. - ✔✔False, they are perpendicular to the equipotentials
Which of the following equipotential mappings is most accurate? - ✔✔The
one that includes non-overlapping lines perpendicular to electric field
State Ohms law - ✔✔V=IR
Create a circuit diagram showing how to connect a voltmeter to measure
the voltage across a resistor that is connected to a battery. - ✔✔Must be
connected across a resistor/ in parallel
Draw a circuit diagram showing how to connect an ammeter to measure
current flow through a resistor that is connected to a battery. - ✔✔Must be
connected through a resistor/in series
, A current of 1 mA flows through a resistor when it has a 2 volt drop across
it. What is the resistance of the resistor? - ✔✔I=1mA, ∆V=2 =>
R=∆V/I=2kΩ
Carefully explain how to set up and connect the multimeter to measure
current flowing through a resistor - ✔✔Break circuit where you want to
measure and reconnect with multi-meter in series
Explain what the horizontal controls do on an oscilloscope. - ✔✔Time
scaling and shifting
Explain what the trigger controls do on an oscilloscope. - ✔✔Determines
precisely when the scope starts acquiring and displaying the input signal to
stabilize the waveform
Explain what the vertical controls do on an oscilloscope. - ✔✔Amplitude
scaling and shifting
Explain how to set up the Measure button so that the scope is displaying a
measurement of the frequency of a signal on channel 1. - ✔✔Measure =>
Source => Channel 1 => Frequency => Add measurement
Explain how to set the wave generator to output a sine wave with an
amplitude of 1 V and a frequency of 10 kHz - ✔✔Wave generator => Sine
=> Frequency=10kHz => Amplitude=1V
