**1.**An example of a simplex transmission where the listener has no path to respond.

A. Telegraph

B. Microwave receiver

C. Public Address System

D. Telephone

**2.**The property of conductors that allows storage of electric charges when potential differences (voltages) exist between the conductors).

A. Inductance

B. Reactance

C. Capacitance

D. Impedance

**3.**The measure of electrical service consumption that a given device is designed to accept. Peak Power is present only twice during a cycle.

A. Wattage

B. Peak Power

C. Impedance

D. Amperage

**4.**An inappropriately large value of measure for analog strength. Instead use the decibel which is One tenth of a bel.

A. Volt

B. Bel

C. Amp

D. Watt

**5.**The formula for computing decibel (dB). Remember that increases or decreases are always at 10 times the original value. This will move the decimal point one place forward or backward. Example: Input is 1W a decrease of 10dB will have a value of 0.1W an increase of 10dB will have a value of 10W.

A. db=10log(p1/p2)

B. db=20log(p1/p2)

C. db=10log(p2/p1)

D. db=20log(p2/p1)

**6**

**.**Allows one amp of current to flow when one volt of electrical pressure is applied.

A. One Joule

B. One Watt

C. One ohm

D. One Volt

**.**Resistance increases as the length of the cable increases. (e.g. doubling the length of the cable doubles its resistance).

A. Length of cable (in reference to conductor resistance)

B. Gauge of cable (in reference to AWG)

C. Capacitance of cable (in reference to farads)

D. Inductance of cable (in reference to henry’s)

**8.**Ohms Law. V is volts. I is current in amperes. R is resistant in ohms.

**A.**V = I / R

**B.**R = V / I

**C.**I = V * R

**D.**P = IR²

**Both IT telecommunications and IT Distributed Computing can transmit over one set of transmission protocols (e.g. ethernet).**

A. Convergence of Traditional Telephony and Distributed Computing (now possible because)

B. Less resistance to the flow of electrical energy

C. Mutual capacitance (for multiconductor cable)

D. Copper Cabling (must be coupled with)

**This represents the power stored by the reactive loads (inductors and capacitors) and is measured in Volt-Amperes Reactive (VAR). This is sometimes called imaginary power.**
