Charlie writes the steps shown to describe the use of a transistor in a closed circuit with flowing current.
using a transistor to amplify a signal
1. current (i1) flows from the base to the emitter.
2. an input causes a small increase in voltage across the base and emitter.
3. i1 increases a small amount.
4. current (i2) flowing from the emitter to the collector changes a large amount.
which change corrects the error in his steps?
change the title to “using a transistor as a switch.”
change step 1 to say that no current flows in the transistor at the start.
reverse the sizes of the changes in current in steps 3 and 4.
reverse the direction of current in step 4.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
