Calculating Total Resistance in a Circuit - Tips and Tricks

AI Thread Summary
To calculate the total resistance in a circuit with resistors in series and parallel, it's essential to identify their configuration. The circuit includes resistors of 25k, 15k, 50k, 40k, and 20k Ohms, with the 50k Ohm resistor in parallel with the 40k and 20k Ohm resistors. A clear description of the circuit connections can help in understanding the arrangement without needing a visual aid. The total resistance can be calculated using the formulas for series and parallel resistors. Providing a diagram or a detailed description of the connections can enhance clarity in such discussions.

I'm wondering how to work out total resitance of a curcuit. The curcuit is made up of Kilo ohms.

25k Ohms
15k Ohms
50k Ohms
40k Ohms
20k Ohms

+ 10 V

I forgot to add that 50k Ohms is parallel to 40k and 20k Ohms.
 
it IS actually possible to give description of a circuit in such a way that we don't need
a picture, but you need to work a bit harder to make it unambiguous.
Something like:

The positive terminal of the battery is connected to termial 1 of R1
Terminal 2 of R1 is connected to terminal 1 of R2
Terminal 2 of R2 is conected to terminal 1 of R3 and terminal 1 of R4
etc.
R1 = 25kOhm, R2=15kOhm etc.

Or you can post or link to a picture

(or post or include a picture)
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
