Question

last one !! yayyyy!

im including both last questions because they are similar.

If each resistor in the circuit shown is 5.0 Ω, and the battery is 12.0 V, what does the second ammeter (A2) read?

0.24 A

0.96 A

0.12 A

0.48 A

first image is for this question

Answer 1

If each resistor in the circuit shown is 5.0 Ω, and the battery is 12.0 V, what does the second ammeter (A2) read?




0.24 A

0.96 A

0.12 A

0.48 A

Answer 2

heres the second question , i believe there somewhat similar ?

Answer 3

i think the first 1 is 4.8 and second is 0.48 ?

Answer 4

Doing the first one and it looks familiar and that's correct

Answer 5

awesome!

Answer 6

Second one also looks familiar but you didn't quite get it

Answer 7

oh no! let me relook at it

Answer 8

What would the total resistance be?

And then plug that into V=IR

And solve for current

Answer 9

R2 and R3 are in parallel, so resistance is (r2 * r3)/ (r2+r3) = 25/10 = 2.5 ohms


the resistance of the entire circuit is R4 + 2.5 ohms + R1 = 12.5 ohms



The current in the circuit V/R = I 12 v/ 12.5 ohms = 960 mA



R2 and R3 split this current 960/2 = 480 mA (or .48 A )

Answer 10

this is what i did

Answer 11

Oh you're right!! I was still looking at the first image and was like 0.48 isn't an answer and you choice 4.8 hahaa

Answer 12

Sorry about that!

Answer 13

But wonderful job!!! You were excellent and hopefully you learned the difference between parallel and series!

Answer 14

oh no i put the question in wrong im sorry! hold on im a bit confused now

Answer 15

let me edit them real quick

Answer 16

heres the 2 different questions, the options are different! i accidentally pasted the same answers

Answer 17

everything looks good in those 2 pics ?(:

Answer 18

i think i wanna do more practice on my own but for the most part i got a way way way better grasp on it! and its you to thank , thank you so much for your help!

Answer 19

They're the same, you got it right!!

Answer 20

Don't mention it, it was an absolute pleasure helping you! And if by any unfortunate chance we accidentally got one wrong, do let me know! No one's perfect and we can always learn from our mistakes:)

Answer 21

you would'nt believe it ! all of them were correct ! YOU ARE AMAZING!!!! thank you thank you!

Answer 22

YAYAYY !!
it was an absolute pleasure 😊
