<li>  One way to operate a 3 volt bulb from a 9 volt supply is 
to connect it in: 

<ol type = a>

<li> series with the supply 

<li> parallel with the supply 

<li> series with a resistor 

<li> parallel with a resistor 


</ol>
<br>

<li>  The total resistance of several resistors connected in 
series is: 

<ol type = a>

<li> less than the resistance of any one resistor 

<li> greater than the resistance of any one resistor 

<li> equal to the highest resistance present 

<li> equal to the lowest resistance present 


</ol>
<br>

<li>  A simple transmitter requires a 50 ohm dummy load. You 
can fabricate this 
from: 

<ol type = a>

<li> four 300 ohm resistors in parallel 

<li> five 300 ohm resistors in parallel 

<li> six 300 ohm resistors in parallel 

<li> seven 300 ohm resistors in parallel 


</ol>
<br>

<li>  The unit for power is the: 

<ol type = a>

<li> ohm 

<li> watt 

<li> ampere 

<li> volt 


</ol>
<br>

<li>  The following two electrical units multiplied together give 
the unit "watt": 

<ol type = a>

<li> volt and ampere 

<li> volt and farad 

<li> farad and henry 

<li> ampere and henry 


</ol>
<br>

<li>  The current in an AC circuit completes a cycle in 0.1 
second. So the 
frequency is: 

<ol type = a>

<li> 1 Hz 

<li> 10 Hz 

<li> 100 Hz 

<li> 1000 Hz 


</ol>
<br>

<li>  The reactance of an inductor increases as the: 

<ol type = a>

<li> frequency increases 

<li> frequency decreases 

<li> applied voltage increases 

<li> applied voltage decreases
