1. Consider the simple circuit in a flashlight that consists of two batteries in series and a single bulb. Which statement below is true about this circuit?
a) Charges move through the circuit quickly, close to the speed of light.
b) The battery is the supplier of the charges that move through the wires.
c) The current that flows in the circuit is used up as it passes through the light bulb.
d) The battery supplies the energy to raise charges from low to high voltage.
e) a and b
f) a, b, and c
g) All of the above
h) None of the above
2. What are the two things you should know about capacitors?
a) With the correctly chosen inductor, resistor, and oscillator, it can be used to broadcast a radio wave of a specific frequency. Also, with the correctly chosen inductor and resistor, it can be used to recieve and amplify a radio wave of a specific frequency.
b) No current flows through it and its net charge is zero.
c) It stores charge and the schematic symbol is two equal length parallel lines, perpendicular to the wires.
d) Whether it stores positive or negative charge depends on its configuration and it can be connected to other capacitors, either in series or in parallel.
e) It has two plates and it is positive and negative.
