Help with this Physics Problem (circuits and current)?
This is my 3rd time asking this question and I appreciate everyone who has tried to help so far. I'm hoping someone can find the correct answer and explain how to do it. Thank you for your help

This is impossible to answer without knowing the resistance of the wire marked A. Using potential divider theory to find the voltage at the junctions at each end of wire A will give you 2 different voltages, let's call the difference Vd.
According to Ohms law, V=IR, so to find current I, you must have both V AND R.
Also, right click your open itunes icon, select 'pin to taskbar' and unpin the unopen one.

It is possible to solve the question Knowing the resistance of Wire A.
the answer will be (6.75-4.5)/ Resistance of wire A

electric contemporary interior the circuit after the swap is closed: i = (V/r)*[ e^-(t/tau)] If time t = tau ===> i = (one thousand/3000)*(e^-a million) = 0.12 A word: The capacitance is used to calculate the time consistent ( tau = RC = a million.5 ms)
