AI Thread Summary
Adding a third resistor in parallel to two existing resistors in a DC circuit will decrease the total resistance, leading to an increase in the total current supplied by the battery. The potential difference remains constant across all resistors, but the current is distributed among them according to their individual resistances. Kirchhoff's Current Law indicates that the total current entering a node equals the total current leaving, which means the battery's current will adjust based on the combined resistance of the parallel configuration. The discussion emphasizes understanding how current distribution and potential difference interact in parallel circuits. Overall, adding a resistor in parallel affects the current flow and distribution in the circuit.

Homework Statement




Let's say i have a circuit with two resistors connected in parallel with some source. Then another resistor is added in parallel with the first two so what happen to the current in the battery?

Homework Equations





The Attempt at a Solution


Should the current in the battery decrease since the potential is split across the three resistors?
 
Physics news on Phys.org
The third resistor is parallel to the other two parallel ones. The common points are connected to the terminals of the battery. So what about the potential difference across all resistors?

Did not you mean that the third resistor is connected in series with the other two parallel ones? ehild
 
No it's is what it is, first there where two in parallel then there was three. The potential difference should the same across all the resistors but current would be distributed, but I'm not sure how this would affect the current going through the battery since the current would meet back up and go through the battery anyways
 
What is the current through a resistor R when the potential difference is V across it?

What does Kirchhoff's Current Law state about the currents at a node? ehild

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 '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...
