Exam 2: Voltage, Current, and Resistance

-The Rotary switch in Figure 2 -1 is most likely to be used as _ _.

If a resistor equals 1.2 Ω ±5%, its color code is _.

Electrons attract each other.

A(n)is a material that has many free electrons.

-Identify the Rotary switch in Figure 2 -1.

A SPST switch is used to control one circuit.

The voltage measured directly across an open switch in a circuit will be:

To measure the current through a resistor, place the ammeter so the current must pass through the meter.

If a resistor is color coded with red, red, orange and silver bands, the resistance equals , the lower tolerance limit equals _, and the upper tolerance limit equals _ .

A resistor color -coded with brown, black and orange bands has a value of 10,000 Ω.

- if you place a voltmeter's red lead on point E and its black lead on point H, you will be measuring .

-Which switch in Figure 2 -1 is usually used to control a doorbell?

-Identify the DPST switch in Figure 2 -1.

Most DMMs will measure _ _ and _.

What do you call a diagram that shows the electrical connections of a circuit's components?

-the voltage VCE is the same as .

A downside of using deep -cycle batteries is

On a resistor with numbers and letters, the position of the letter in the sequence represents:

For electrical current to flow in a circuit, voltage must be applied to that circuit.

Interpret the following mixed numbers and letters 4R7 on a resistor to the correct resistance of:
