EWITS Lessons 1-5

​ (a)   is the flow of 

charge in a circuit. The  

current is ​ (b)   regardless 

of where it is measured and  

is not lost or used up in the  

system. 

• Current
• the same
• Voltage
• different

The current registered 

on the ammeter is ​ (a)  

regardless of where it is placed 

in the circuit. 

• the same
• different

The current  

will be ​ (a)   if more batteries  

are placed in the circuit. 

• higher
• lower

Batteries connected in series affect current ​ (a)    

​ than batteries connected in parallel.

• the same
• differently

Adding batteries in series 

substantially ​ (a)   the number of charges  

flowing in the system, whereas adding batteries in  

parallel ​ (b)   (or the increase is not substantial).

• increase
• does not
• decrease
• does

As you add batteries in a series, current ​ (a)   .

• increases
• decreases

The voltage measured in a one-battery system was 1.4 V. Voltage measured for circuits using batteries in series was ​ (a)   for a two-battery system and ​ (b)   for a three-battery system. 

• 2.8 V
• 4.2 V
• 1.4 V

The brightness of a lightbulb varies ​ (a)   with the voltage across it. As the voltage increases, so, too, does the ​ (b)   of the lightbulb. 

• directly
• brightness
• indirectly
• dimness

In a parallel battery set up as the number of batteries increase, the voltage ​ (a)   .

• stay the same
• increases
• decreases
