Resistance in a wire - Simulation

By Sandile MHlophe -

 

Topics

  • Resistivity
  • Resistance
  • Circuits

Description

Observe changes to the equation and wire as you play with the resistivity, length, and area sliders.

Sample Learning Goals

  • Predict how changing each variable will affect the resistance.
  • Explain the difference between resistance and resistivity.

Do we have free-will?

By Sandile MHlophe -
 Are you free?  we often think we are free but are we really free? this question sounds so simple yet it is actually not. What does it even mean to be free? Well in this post I will explain to the best of my knowledge what is free will and whether we have it or not. can you escape fate? Let's consider the story below: When Thabiso was born a prophet foretold that he would grow up to kill his father and then marry his mother. His father fearing for his life decided to leave the baby in the wilderness with the hope that he will die, thefore the prophecy will not come  true. The baby was found by another couple, and grew up knowing them as his parents. The boy heard of the prophecy, not knowing his adopted and because he loves his father(adopted) he decided to go away from his family to avoid the prophecy. In the way he met and killed a man and then felt bad for the wife of this man, he decided to marry her. The man he met is in fact his fat...

Ohms law - Simulation

By Sandile MHlophe -
  Topics Ohm's Law Circuits Current Resistance Voltage Description See how the equation form of Ohm's law relates to a simple circuit. Adjust the voltage and resistance, and see the current change according to Ohm's law. Sample Learning Goals Predict how current will change when resistance of the circuit is fixed and voltage is varied. Predict how current will change when voltage of the circuit is fixed and resistance is varied.

 Umlingiswa ongummeleli emdlaweni othi, Kudela Owaziyo. ISINGENISO  Ummeleli ngumlingiswa oyiqhawe lomdlalo.  Indaba yonke incike kuye. Yize engekho kwezinye izehlakalo kodwa ziyamthinta ngandlela thize. Indaba yonke imayelana naye. Ubhekana nenkinga ethile ashikashikeke ezama ukuyixazulula. Kuyenzeka aphumelele noma ehluleke.

Why liminal spaces are uncertain and ambiguous

Why liminal spaces are uncertain and ambiguous and promote a feeling of communitas amongst the people who occupy these spaces.  Posted by  Sikhanyisiwe Mkhonto We are constantly moving from one space to another. These are often large socially constructed spaces that create meanings or serve a function in our society. There are however spaces where we are neither in nor out. This space is the centre of two large spaces. A small space where one feels connected with the fellow members who are occupying that small space in that moment (Shortt, 2015: 634). Turner investigated the works of Arnold Van Gepp who spoke of the concept of ‘rite de passage.’ Victor Turner’s focus was the liminal period of a ritual. ‘Liminality is ambiguous, this is because the individual is not being classified into any category which confirms their role in a cultural society’ (Turner, 1969: 95). In this liminal period members involved experience a sense of harmony, this is what Turner labels as communit...

Curve Fitting - Simulation

By Sandile MHlophe -
  Topics Polynomials Error Analysis Data Description Drag data points and their error bars and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, or cubic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.

Success code...

By -
 Our success may not be “success” to someone else and vice-versa. Be careful who you listen to and who you surround yourself with. Because oftentimes, we create this “mental picture” of what success looks like but when we listen to those around us and THEIR expectations of success, we start to question our standard of success. Always look to those above you and strive to reach them, but never forget about those below you and treat them unjustly. Focus on YOUR personal and relative meaning of success and your life will start to take meaning. You have something special. You have GREATNESS within you. BP Masombuka
