WebOhm’s Law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions, such as temperature, remain constant. WebUse a variable resistor in series with the resistor to vary the potential difference across the resistor. Start with a potential difference of zero and increase the potential difference by an interval of 0.2V up to 2V. Recording the readings on the voltmeter and ammeter. Reverse the connections on the battery and repeat steps 4 and 5 to find ...
WebOhm expressed his discovery in the form of a simple equation, describing how voltage, current, and resistance interrelate: In this algebraic expression, voltage (E) is equal to current (I) multiplied by resistance (R). Using algebra techniques, we can manipulate this equation into two variations, solving for I and R, respectively: WebAug 15, 2024 · Ohm’s law in this form really defines resistance for certain materials. Ohm’s law (like Hooke’s law) is not universally valid. The many substances for which Ohm’s law holds are called ohmic. These include good conductors like copper and aluminum, and some poor conductors under certain circumstances.
