When an electric heater is turned on, the Nichrome heating element is at 0° C and draws a current of 14 A, with a potential difference of 120 V between the ends of the element. The element heats up to 744° C, with the potential difference constant. Find the final current. (The temperature coefficient of resistivity of Nichrome is 4.0 10-4 (°C)-1.)
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.
