AI Thread Summary
The discussion focuses on calculating the power supplied by a dependent current source given V1=10 V and ix=-2 A. The correct power calculation yields -60 units, indicating that the current is flowing from the negative to the positive terminal, consistent with conventional current flow. There is confusion regarding the interpretation of signs in power calculations, as some believe the negative signs should cancel out. However, the power delivered is accurately calculated as V multiplied by the current, confirming the negative value. Understanding the direction of current flow and its relation to power calculations is crucial for clarity in these scenarios.

Homework Statement



In the Figure below if V 1=10 V and i x= -2 A, what is the power supplied by the dependent current source?




Homework Equations





The Attempt at a Solution



The answer is -60. But I am getting 60. whenever It's power supplied doesn't it mean the current is entering from the negative end of the voltage ? like shown in the diagram? So shouldn't the negative signs cancel out? I am really confused.

Current flow is caused by electrons. Electrons originate from the negative terminal of a battery. But conventionally, the direction of current is taken in reverse. That is, external to the battery, it's from + to -, or in other words, from - to + inside the battery.

In the question, direction of current is from - to + inside the source. So the given polarities are proper and power delivered = VI= V1 * 3 Ix
= 10 * 3 * -2
= -60 units.

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...
