a. s
b. In a serie it is round so everything go in one direction, while in a parallel circuit splits up and comes
    back together later, so half goes one side while the rest goes the other.
c. ?
d. When the energy gets too high that something may go wrong, the fuse will melt and the circuit won’t
    work anymore.
e. The voltage gets higher :/

Q1, Kinetic energy

Q1, because in a AA fit more electrons which are all locked up in a high concentration, so it takes longer
       for all those electrons to go the low concentration.

2. The flat battery had used up all the chemicals inside it, while in the new battery all the chemicals are
    still there.
3. You have solar panels, you can usually find them on roofs since there is less shadow to stop the light
    from going on the solar panels.

Q1, A dynamo takes the speed on the wheel to turn round, the dynamo uses the speed to create light  
      energy. But the dynamo has to be pushed against the wheel, and works exactly the same a the bricks,
     but the bricks press harder.
Q2, Two 60 W lamps, because if you add the W together it becomes

1. Fuel
2. Uranium
3.

Q1, Series
Q2, Parallel

1. Current - Ammeter - (A) - Serie
    Voltage - Voltmeter - (V) - Parallel
2a  2V
2b  Lamp A

Q1, b

1a  Battery, Plug
1b  Lamp, speakers, clock

3. Well the plug supplies the cable with electrons, the electron go through the wire (road), and are used  
    up by energy using components (people who want milk), at the end of the cable (route) the energy
    (milk) should be gone.

4. The street lights transform electrical energy to light energy, cars (which are invisible) transform chemical energy to kinetic energy, The church or whatever it is probably contain some heater, lights, speakers, clocks. Heaters transform electrical energy to heat energy. Lights transform electrical energy to light energy. Speakers transform electrical energy to sound energy. Clocks transform electrical energy or potential energy to kinetic energy.

  b. Electrical
  c. Chemical potential, light and a bit of heat
2. Volt meter
3. Volts
4a. The red big panasonic, it's bigger because there are more chemicals inside, which will cause more energy.
  b. Because it says "Long Life" on the smaller battery
