Understanding Ohm’s Law: Exploring Voltage, Current, and Resistance



In this informative video, we dive deep into the fundamental concepts of electrical circuits. Join us as we unravel the mysteries of current, voltage, and resistance. Learn how current is measured in Amperes (amps), the potential difference in volts, and the resistance in ohms. By drawing parallels to the flow of water through a pipe, we simplify these concepts, equating water pressure to voltage and the volume of water to amperage. Discover the significance of resistance, akin to friction in the pipe, hindering the flow of current. We also explore Ohm’s Law, a cornerstone of electricity, which mathematically relates voltage, current, and resistance. Find out how this law highlights the proportional relationship between current and voltage. Join us on this journey of understanding electrical basics, as we demystify amps, volts, and ohms. Watch now and grasp the core principles that underpin the world of electrical circuits!

  1. All I got from this is with electricity, the flow is measured in amperes, and water (as a comparison) is measured in volts. Shouldn't it also be in amperes to avoid confusion? I don't get it

  2. I'm sure some African culture discovered this, and applied it's principles to invent amazing inventions that benefitted all of mankind.
    Yeah…all cultures are equal. . 😂😂

  3. Difference in potential… Does that mean You start from zero volts and go to 12? Zero to 480? I'm having a hard time understanding the "difference in potential"

  4. This is all well and good, but current is the flow of electrons and electrons flow from positive to negative in a battery (DC) so in the circuit they flow from negative to positive

  5. E=I×R
    I=E/R
    R=I/E
    Super confusing at first.. I just co vert it over to VAR so I can keep track of what I'm doing instead of changing terminology and confusing myself

  6. An "ohm" (symbol: Ω) is a unit of electrical resistance in the International System of Units (SI). It measures how much a component or material resists the flow of electric current. One ohm is defined as the resistance of a conductor in which a current of one ampere flows when a voltage of one volt is applied. The concept of ohms is fundamental in Ohm's Law, which states that voltage (V) equals current (I) times resistance (R):
    V
    =
    I
    ×
    R
    V=I×R.

    Edit: I type this for 1 sec
