makeup of a conductor, insulator, semi-conductor
< 4 electrons in valence band
> 4 electrons in valence band
4 electrons in valence band
If little Theo built a DC circuit that allowed 1 amp of current flow to enter through 5 resistors, how many amps would exit the circuit?
1
What is the best method of wire splicing and what are the materials used?
Soldering
Rosin Core
One-way check valve that is adjustable
Zener Diode

a direct short
What would the resistance reading be of a circuit with
12 volts of pressure and 1 amp of current flow?
12 ohms
switches electricity multiple times in multiple directions in a second.
transistor
Electricity flow of an alternator to the battery
+ to +
Parts of a circuit
Power Source, Safety Device, Controlling Device, Path, Load, Return.
A closed loop. With an ohm-meter.
What would the voltage reading be while measuring across a good fuse in a normal automobile electrical system?
0 volts
Solenoid
When the contacts open in the primary circuit ....
The electricity bounces back (back EMF) and through induction, electrons jump to the secondary circuit and complete the path to the spark plugs
A Coloumb
= 1 Amp; 600,000,000 electrons moving past one inch in one second
OL is the reading on a DVOM. What does it mean?
An infinite amount of resistance is present
What are the color codes for connectors and what are the wire sizes that match them?
Red = 16-22
Blue = 12-14
Yellow = 10
Step-up transformer in an ignition system
Coil
When electricity reaches the starter solenoid......
2-things happen:
1-The contacts of the starter motor close and the motor starts spinning.
2-The pinon gear meshes with the ring-gear to start cranking the engine.
