QUIZ
1. The antenna in the Remote Control Transmitter converts electrical energy into . . . . .
A - radio energy.
B - mechanical energy.
C - geothermal energy.
D - nuclear energy.
2. The commands to be sent from the Remote Control Transmitter are encoded onto a sequence of electrical pulses by
changing . . . . .
A - the spacing between the pulses.
B - the duty cycle of the pulses.
C - the number of pulses in the sequence.
D - the amplitude of the pulses.
3. On some models the Remote Control Transmitter only sends Left/Right commands if Forwards/Backwards commands
are also being sent because . . . . .
A - The left/right lever is not electrically connected to anything.
B - Otherwise the transmitted signal would be too weak to be picked up by the car.
C - Otherwise the transmitter would interfere with your TV reception.
D - there is to much friction to turn the front wheels unless the car is moving.
4. If there is an obstacle between the Transmitter and the car then radio energy can travel to the car by going . . . . .
A - through the obstacle.
B - around the obstacle.
C - both A and B.
D - not possible, the obstacle blocks radio reception completely.
5. If the batteries in the RCC-7K are weak, the main effects you will notice are . . . . .
A - reduced remote control range and reduced power to the motor.
B - the light bulb blinks to tell you to change the batteries.
C - interference with your TV set.
D - the car goes faster.
6. The first stage of the receiver is basically a . . . . .
A - speaker.
B - integrated circuit.
C - power supply.
D - filter.
7. Using less synchronization pulses or less pulses to represent each of the transmitter commands makes . . . . .
A - it take longer to transmit each command.
B - the transmitter battery last a lot longer.
C - the car more likely to activate on random noise.
D - the car go faster.
8. Reversing the voltage to the steering motor will cause . . . . .
A - the motor to explode.
B - the motor and the car to turn in the opposite direction.
C - the motor to spin faster.
D - the motor to stop spinning.
9. Interlocking gears . . . . .
A - spin in the same direction.
B - serve no useful purpose.
C - jam together and prevent each other from spinning.
D - spin in opposite directions.
10. To spin the rear wheels once, the driving motor must spin . . . . .
A - 100 times.
B - 20 times.
C - 9 times.
D - 4 times.
