Answer the following question using this image.
5
Multiple Choice
What type of circuit is this?
Series
Parallel
Serie Parallel
6
Remember a series circuit only has one path from power to ground.
- Total Resistance = The sum of all resistors
- Amperage is the same everywhere on the circuit.
7
Parallel Circuits
Multiple Paths from power to ground
At least one load on each branch
Amperage is different for each branch depending on resistance per branch.
8
Fill in the Blank
An automotive battery generates how many volts?
9
Multiple Choice
This electrical term is also referred to as the flow of electricity.
Amperage
Resistance
Voltage
Wattage
10
Multiple Choice
This electrical term is the opposition to the electrical flow.
Resistance
Amperage
Voltage
Watts
11
Ohms Law
Voltage = Resistance X Amperage
Resistance = Voltage / Amperage
Amperage = Voltage / Resistance
12
Multiple Choice
If resistance decreases on a series circuit will amperage increase or decrease?
Increase
Decrease
13
Multiple Choice
If voltage increase on a series circuit will amperage increase or decrease?
