335. Power
Connect points E and F with a 4-wire (4) in project #332. Press the
press switch (61) for a while and you will hear space battle sounds.
Release the press switch (61) and wait for a while. You will eventually
hear the space battle sounds start breaking up and fading out. Power
is the rate of doing work, or the energy transferred per unit of time.
Mathematically, Power = Work/Time.
336. Watts
Connect points G and H with a 4-wire (4) in project #332. Press the
press switch (61) for a while and you will hear music. Release the press
switch (61) and wait for a while. You will eventually hear the music start
breaking up and fading out. Watts is the unit of measure for power
dened as 1 Joule per second.
337. Einstein’s E = mc
2
Replace the press switch (61) with the reed switch (83) in project
#332. Hold the magnet (7) near the reed switch (83) for a while
and you will hear the siren. Move the magnet (7) away from the reed
switch (83) and wait for a while. You will eventually hear the siren start
breaking up and fading out. You may have heard of Einstein’s formula
of E = mc
2
where E is Energy, m is mass and c is the speed of light.
This formula states that the Energy and Mass are related, and if the
mass of an object were to be completely converted to energy, then the
energy it would create would be equal to it’s mass times the speed of
light squared.
338. Alessandro Volta
Connect points C and D with the 1kW resistor (42) in project #337.
Hold the magnet (7) near the reed switch (83) for a while and you
will hear gun shots. Move the magnet (7) away from the reed switch
(83) and wait for a while. You will eventually hear the gun shots start
breaking up and fading out. Did you know that Alessandro Volta invented
the rst battery, the voltaic pile, in 1800? The very rst circuits used a
battery and electrodes immersed in a container of water.
