Webb14 apr. 2024 · Here is the figure mentioned above. My thinking is that for maximum current, resistance must be minimum. Thus, R1 is not considered which means the voltage drop of R2 is 10V. So, R1 is 1kohm. For minimum, I=2A, so R1+R2=5kohm, since R1 is 1kohm, R2 must be 4kohm. This is how I deduce. However... WebbWeb ohm ohms lessonplanet greater ohms legislation worksheet answers.

WebbThe Ohm's law equation is often explored in physics labs using a resistor, a battery pack, an ammeter, and a voltmeter. An ammeter is a device used to measure the current at a given location. WebbOhm’s law states that the voltage across two points in an electric circuit is directly proportional to the current passing between those two points. The constant of …

Webb2 jan. 2024 · Ohm’s Law The dependence of current on potential difference can be studied by Ohm’s law. According to Ohm’s law, the potential difference (V) across the ends of a resistor is directly proportional to the current (I) through it provided its temperature remains the same. i.e. V ∝ I or V/I = Constant = R or V = RI http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html
