Another Q if anyone has time:
If I have a circuit like this:
and I need to get Rac (I already have Rab) how do I draw my new diagram to determine whether R1 is parallel or in series with Rab? I guess a better way to ask is: when you have a combined Resistance Rab, how do you determine where...
I was able to solve it by using R3 instead in series with R1:
Requiv = R1 + R3 = 42 Ohm + 119 Ohm = 161 Ohms
I = V/R and I equiv = I1 = I3
12V/161 Ohms = .0745341615 A
However, I am kind of fumbling through it so any insight you can give me regarding why my previous attempt at a solution was...
That is the first Q on the homework assignment. If it was irrelevant I apologize but I thought it might provide context for what I was attempting to do.
Are you saying that they are in series and not in parallel? If so I am way more confused than I thought I was.
Wouldn't the voltage just be...
Homework Statement
[/B]
R1 = 42 Ω
R2 = 124 Ω
R3 = 119 Ω
R4 = 105 Ω
Rx = ?
I4 = O A
Homework Equations
R = IV
V = V1 = V2 for parallel Resistors
Iequiv = I1 +I2 for parallel Resistors
Vequiv = V1+V2 for series Resistors
Iequiv = I1= I2 for series Resistors

I have...
A mass m = 6.2 kg hangs on the end of a massless rope L = 1.96 m long. The pendulum is held horizontal and released from rest.
1) How fast is the mass moving at the bottom of its path?
I calculated this to be 6.201 m/s using the equation v=√(2gh) (correct)
2) What is the magnitude of the...
