• current
• resistance

Ohms are a measurement of electrical __________________.

• power
• pressure
• current
• resistance

Total resistance is the sum of all resistors in a _________________ circuit.

• series
• complex
• parallel
• closed

A parallel circuit has 2 branches, and each branch is 20 ohms, the total resistance is _______.

• 10 ohms
• 20 ohms
• 40 ohms
• 15 ohms

Amperage is the same at all points in a _________________ circuit.

• series
• complex
• parallel
• open

The formula for calculating current is:

• I=E/R
• R=E/I
• I=E*R
• W=I*R

When the component is isolated from power, you are testing:

• current
• voltage drop
• power 
• resistance
