<li>  Six identical 2-volt bulbs are connected in series. The 
supply voltage to 
cause the bulbs to light normally is: 

<ol type = a>

<li> 12 V 

<li> 1.2 V 

<li> 6 V 

<li> 2 V 


</ol>
<br>

<li>  Five 10 ohm resistors connected in series give a total 
resistance of: 

<ol type = a>

<li> 1 ohm 

<li> 5 ohms 

<li> 10 ohms 

<li> 50 ohms 


</ol>
<br>

<li>  A 5 ohm and a 10 ohm resistor are wired in series and 
connected to a 15 
volt power supply. The current flowing from the power supply 
is: 

<ol type = a>

<li> 0.5 ampere 

<li> 1 ampere 

<li> 2 ampere 

<li> 15 ampere 


</ol>
<br>

<li>  When two 1000 ohm 5 watt resistors are connected in 
parallel, they can 
dissipate a maximum total power of: 

<ol type = a>

<li> 40 watt 

<li> 20 watt 

<li> 10 watt 

<li> 5 watt 


</ol>
<br>

<li>  A resistor of 10 kilohm carries a current of 20 mA. The 
power dissipated in 
the resistor is: 

<ol type = a>

<li> 2 watt 

<li> 4 watt 

<li> 20 watt 

<li> 40 watt 


</ol>
<br>

<li>  The 'rms value' of a sine-wave signal is: 

<ol type = a>

<li> half the peak voltage 

<li> 1.414 times the peak voltage 

<li> the peak-to-peak voltage 

<li> 0.707 times the peak voltage


</ol>
<br>

<li>  Increasing the number of turns on an inductor will make 
its inductance: 

<ol type = a>

<li> decrease 

<li> increase 

<li> remain unchanged 

<li> become resistive
