Physics: Voltmeters and Ammeters
Learn about the instruments we use to measure voltage and current
Physics
Learn about the basic principles that govern the physical world around us. Solid understanding of algebra and a basic understanding of trigonometry necessary.
Ohm's law and circuits with resistors
In these videos and articles you'll learn how Ohm's law relates the voltage across a resistor, the current through a resistor, and the resistance of the resistor. You'll also learn how resistors in series and parallel combine to form an equivalent resistance. The resistivity of materials, power used by a resistor, and how to use voltmeters and ammeters will also be discussed.
