If 2.6 x 10^18 electrons and 7.3 x 10^18 protons move in the same directions past a given cross-section of a hydrogen discharge tube every second, the average current (in amperes) in the tube is ______. CHOICES: 0.39. 0.75. 0.83. 1.59. 3.49.
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.
