The resistance of the tungsten filament of an incandescent light bulb at 24 degC is 32 Ohms. If the light bulb is connected to a voltage of 130 V a current of 0.3 A flows through the filament. What will be the temperature of the light bulb filament under working conditions? The temperature coefficient of resistance of tungsten is 4.6E-3 1/degC. Your answer must be in degC, other scales are not accepted.
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.
