Electric Cells and Current Electricity

video lesson SS3 · Physics · 42:15

The lesson covers the types of electric cells, including primary and secondary cells. It explains the concepts of electromagnetic force, current electricity, potential difference, and resistance. The arrangement of cells in series and parallel is also discussed.

  • 07:58 “That means we have I total is equal towards I1 plus I2 plus I3 and so on and so on, there are many of it. We are told that they have equal potential difference, that is we have V total is equal to V1, is equal to V2, is...”
  • 08:49 “We have principal potential meter, now this is a device that is prepared to measure potential difference. It is apparatus commonly used to measure and or to compare the EMF, to compare EMF. It can also want to compare th...”
  • 10:32 “Now, we have this from the resistivity, we have resistivity is direct proportional to the length and inversely proportional to the area. That is, we have this by removing this proportionality sign, we have, which is equa...”

Fundamental and Derived Quantities

video lesson SS1 · Physics · 26:41

This lesson covers the definitions of fundamental and derived quantities in physics. It explains how fundamental quantities serve as the base for deriving other quantities and the importance of measurement in physical science.

  • 26:16 “and the fifth one resistance of the resistor and the last one, which is capacitance of capacitor. Thank you for watching. My name is Tijani Musa, Ola de Krupo. See you next time.”
  • 11:04 “should you come across it in another textbook for further research. Pleasure. Pleasure is given as force per unit area. So the force of an object over the area, don't forget that the force is the same thing as weight. Th...”
  • 10:17 “So this is major in kilogram and this is meter per second squared. So more meter per second squared is equivalent to new thing because we surely discussed this in this subsequent class. At the same time, this new thing w...”
