    Circuits Symbols
AI Thread Summary
The symbol Zach encountered in his circuit represents a ground connection, which indicates that the voltage at that point is set to zero volts. This grounding affects the entire circuit by establishing a reference point for potential. Consequently, all components connected to that ground point will have their voltages measured relative to zero. Understanding this concept is crucial for analyzing circuits in Physics 2 E&M. Grounding is a fundamental aspect of circuit design and analysis.

I am currently working a problem just as practice for Physics 2 E&M and I came across a symbol in one of the circuits that looks like this

I am not really sure what it is but after reading for a little while, I saw something about it signaling that the circuit is grounded at that point?

If so would this cause everything from that point on to have zero potential?

Any help would be appreciated!

Hi Zach! Welcome to MHB! :)

I take it you mean this symbol:

Yep. That means ground.
It sets the voltage at that point to a reference of zero volts.
 
Thread 'Video on imaginary numbers and some queries'
Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Thread 'Unit Circle Double Angle Derivations'
Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
