To B or not to B
Going in circles?
100
Current
What is Amperes
100
Write the equation for Ohm's Law.
What is I = V/R
100
Which of the following will cause the current through an electrical circuit to decrease? Choose all that apply. A. Decease the voltage. B. Decrease the Resistance C. Increase the voltage. D. Increase the Resistance
What is A and D.
100
This is the cause of magnetism.
What is moving electric charge.
100
If a satellite is launched from Earth at 8 km/s, what kind of orbit will it enter?
What is a circular orbit?
200
Electric Potential
What is Volts
200
An electric toothbrush has a resistance of 3 ohms and a current of 4 amps. What is the voltage through the electric toothbrush?
What is 12 volts.
200
Draw a circuit using proper symbols consisting of a battery, wire, a switch, and 2 resistors in series.
What is resistors should be next to each other. See notes.
200
True or false. A magnetic field could be produced by a moving proton.
What is True. A proton has an electric charge. If it is moving, it will create a magnetic field around itself.
200
The space shuttle and the Hubble telescope usually hang out in low earth orbit. About how long does it take for these objects to go around the earth one time?
What is 90 minutes.
300
Energy
What is Joule
300
An electric heater gets 120 volts from an outlet and draws 10 amps of current. What is the heater's resistance?
What is 12 ohms.
300
Draw a circuit diagram consisting of 2 batteries wired in series connected by wire to two resistors wired in parallel.
What is see notes.
300
A term which describes the fact that the geographic and magnetic north and south poles are not located in the same place.
What is magnetic declination.
300
We all know that the moon goes around the earth. However, if the earth and its gravitational pull suddenly disappeared, what would the moon do?
What is fly off in a straight line.
400
Force
What is Newton
400
A flashlight is powered by a 3 volt battery and uses a bulb with a resistance of 6 ohms. What is the current through the flashlight?
What is .5 amps.
400
The two requirements that must be met in order to establish an electric current through a wire.
What is a closed conducting path and voltage (potential difference).
400
A device that allows voltage to be stepped up or stepped down in an AC circuit. Daily Double!
What is a transformer. Who invented the transformer? (200)
400
Satellites in this type of orbit hover over the same spot on earth and look like they are not moving, but they really are! What do we call these types of satellites? Daily Double.
What is Geostationary. Tell me why these satellites appear stationary even though they are moving. (100) Tell me what types of satellites use this type of orbit (100).
500
Charge
What is Coulomb.
500
What kind of current do batteries create when they are used in a circuit?
What is DC.
500
You have likely been warned to avoid contact with electrical appliances when your hands are wet. Why?
What is because your resistance will be lower when your hands are wet.
500
If a magnet is moving into and out of a coil of wire, what is created across the coil of wire?
What is voltage. (If you have a closed loop of wire, and changing magnetic field creating voltage, then you have met the two requirements you need to create current. Current is a secondary result...the voltage is created first.)
500
If I launch a satellite from earth at 12 km/s, what kind of orbit will it achieve?
What is no orbit. It will escape.
