Engineering Electric Circuits: Current & Charge in 30 Secs

AI Thread Summary
The current in an electric conductor is given as 2.4 A, which can be expressed as 2.4 C/s. To find the total charge passing a point in a 30-second interval, this value is multiplied by the time duration. The calculation results in 72 coulombs (2.4 C/s * 30 s = 72 C). The method used for the calculation is confirmed to be correct, with clarification on the relationship between amperes and coulombs per second. Understanding this relationship is essential for solving similar problems in electric circuits.

Homework Statement


If the current in an electric conductor is 2.4A, how many coulombs of charge pass any point in a 30 second interval?


Homework Equations


A = C/s


The Attempt at a Solution


I just want to make sure that I am doing this right. If my current is 2.4 A then I can write this as 2.4 C/s and then multiply by the 30 second interval.
2.4 X 30 = 72 Coulombs is this the correct method?
Thanks

I would be careful how you state your expression. I think you meant 1 A = 1 C/s. Is that right? The rest of your thought process looks correct to me.

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
