The resistance of each brake lightbulb on an automobile is 7.4 Ω. Use the fact that cars have 12-V electrical systems to compute the current that flows in each bulb if they are connected in series.
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.
The resistance of each brake lightbulb on an automobile is 7.4 Ω. Use the fact that cars have 12-V electrical systems to compute the current that flows in each bulb if they are connected in series. (For simplicity, assume that the circuit is only composed of one brake lightbulb and the car battery.)
