Consider a resistor of resistivity 3.12 × 10-5 Ω • m, length 17.89 m, and unknown cross-sectional area. What potential difference, in millivolts, should be applied across the said resistor so the current density in it is 41.62 A/m2? Express answers accurate to four decimal places.
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
