∙ 6y agoOhm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. Mathematically, it is expressed as I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.
Ohm's Law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. Mathematically, it can be expressed as I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.
If a lightbulb has a resistance of 250 ohms, the voltage required for the bulb to draw a current of 0.5 A is 125 V. (Ohm's law: voltage equals current times resistance)Unfortunately, its more complicated than that...Is the resistance of 250 ohms the hot resistance or the cold resistance? It matters. It matters very much.Light bulbs have a dramatic positive resistance to temperature coefficient. It is not uncommon for the instantaneous on power to be 10 or 20 times the nominal value.So, if the 250 ohms is the measured resistance while operating at a current of 0.5 A, then 125 V is the correct answer. If the resistance is the cold resistance, you need to go back and find out the hot resistance at the desired operating point.
The unit of Ohms was named after the German physicist Georg Simon Ohm, known for Ohm's Law which relates the voltage across a conductor to the current flowing through it.
The voltage required can be calculated using Ohm's Law, V = I * R, where V is the voltage, I is the current (3 amps), and R is the resistance (4 ohms). So, V = 3 * 4 = 12 volts.
Newton's second law states that the acceleration of an object is directly proportional to the net force applied to it, and inversely proportional to its mass. This can be mathematically represented as F = ma, where F is the net force, m is the mass of the object, and a is its acceleration.
Ohm's Law states that 'the current flowing along a conductor is directly proportional to the potential difference across the ends of that conductor, providing all physical conditions, such as temperature, remain constant'. Unfortunately, Ohm's Law applies to very few conductors and, so, hardly qualifies as a 'law' at all!
ohms law.
To find the conductance using ohms law,you take the inverse of the resistance(/R)
The correct answer is LAW.
