Question

im working on filling this table for a parallel circuit, i dont know if it would be to much to ask you to check them all but , i think i may have done an error in the column that says "sum of currents" or "total voltage"

I have attached the circuit with both 1 resistor and 2 , so you can see that data for the table and as well the table that i think i did correctly.

It would be a huge help! thank you so much

Answer 1

if you just want to check the sum of currents and total voltage i understand!

Answer 2

@TheSmartOne , if you could possibly help me ?

Answer 3

Okay so just looked at it and figured out that diagram

Answer 4

In parallel resistors

Voltage stays the same and current changes

So your row for two resistors starts off wrong because you divided the voltage by 2 and not the current
You weren't supposed to change the voltage since that will stay the same

Also in your diagram it says the resistors are 3 Ohms in that one cell under the diagram
I'm not sure why you put down for both rows that the resistor was 5 ohms

Sum of the currents should end up being the same as the total measured currents
I'm not sure how you needed up with 75

And similarly for voltage

And then equivalent resistance, I have no idea what this is but shouldn't it just be 3 ohms?

Answer 5

ended up*

Answer 6

And similarly for total voltage, I don't think it should change from the 15 V

Answer 7

Maybe equivalent resistance is basically asking for the sum of the resistors

Answer 8

hmm okay, well for the first column i found the current to be 5 and 10 . i think you may be right that the 2nd colum would be 15 and 15

i put 5 because of the 5 volts at the top

Answer 9

Well would the first column really be 5 and 10?

Those are are the total currents, but is that also the current for each resistor?

And the 5 volts that you say (15 volts you mean?)
Well anyways, it's not the resistor value which is given as 3 ohms

Answer 10

How'd you get resistance of 0.2

Answer 11

equivalent resistance i think is the the value of 1 resistor and the number of indivisual resistors so 5/1 =5 for 1 resistor and 5/2 = 2.5 for 2 resistors.

Answer 12

wait your right it is 3

Answer 13

So the first column should be 5 and 5

The total current in the one resistor is 5 so the one resistor only has 5 A going through it

The circuit with two resistors has a TOTAL of 10 (5+5). It's even in the diagram
And so how much current would be going through one resistor?

Answer 14

this is the correct equations, can we go one by one , instead of jumping all over the place. It has made me very confused. im so sorry

Answer 15

Sure, so the first column that says current through one resistor

When we only have one resistor, that would be a series circuit
When we have two resistors then it would be a parallel circuit

So what would be the current going through one resistors on both circuits?

Answer 16

hi , im sorry it has been hectic today, but i ended up figuring out how to do all of them and got it all correct. thank you though for your help! We were on the right track

Answer 17

That's awesome!! And no worries! Glad to be of some help:))
