A car battery does 360 J of work on the chargepassing through it as it starts an engine. (a) If the emf of the battery is 12 V, how much charge passes through the battery duringthe start? (b) If the emf is doubled to 24 V while the work remainsthe same, does the amount of charge passing through the batteryincrease or decrease? By what factor?
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.
