4.) Three 20- resistors are connected in series to a 9-V battery. What is the voltage difference across each resistor?

5.) Three resistors of 5 , 10 , and 2 are connected in parallel with one another. What is the equivalent resistance of this combination? Enter the unit as "ohms".

6.)Three identical resistnaces, each 24 , are connected in parallel with one another and the combination is connected to a 12-V battery (See E12 Diagram on page 280 of your textbook). How much current flows through each resistor in this combination?

I've tried:

#4.) V=IR convert to I=V/Rseries

Rseries= R1 + R2+ R3 which is

2+2+2=6. then I took I=9V divided

by6. so I=1.5V....( get 3 tries on

online homework, it said 1.5 isn't

right, and im not sure what I had

done wrong.)

#5.) I did 1/Rparallel = 1/R1 +1/R2

+ R3. soo 1/Rp= 1/5+ 1/10 +1/2=

1/Rp=0.8...then I get 0.8ohms.

#6.) and for this one I did same as

number 5. but change the numbers

to: 1/Rparallel= 1/24+ 1/24 + 1/24.

1/Rparallel=0.125...I put it in

the I=V/R equation, so I=12v/0.125 and I get 96A
