Circuits Parallel Series

AI Thread Summary

To calculate equivalent resistance in mixed circuit configurations, it's essential to identify which resistors are in series and which are in parallel. For resistors in parallel, the formula is 1/R_eq = sum of(1/R_individual). The confusion often arises when combining series and parallel resistors; series resistors simply add their resistances together. It's crucial to simplify the circuit step by step, calculating the equivalent resistance of parallel groups before combining them with series resistors. Understanding these principles will clarify the calculation of equivalent resistance in complex circuits.

How can you separate the series and parallel in this combination?? I'm confused... the question asks for equivalent resistance

I thought it's somelike like this:

1/R eq = 1/2R(1) + 1/R(1) + 1/R(2)

but it's wrong...help?

Just some guy

I can't see the picture, but for resistors in parallel 1/(total resistance) = sum of(1/induvidual resistances)

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
