Batteries are rated in terms of ampere - hours (A ⋅ h). For example,a battery that can deliver a current of 3.0 A for 5.0 h is ratedat 15 A ? h. (a) What is the total energy, in kilowatt - hours, storedin a 12 - V battery rated at 55 A ⋅ h? (b) At $0.12 per kilowatthour,what is the value of the electricity that can be producedby this battery?
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.
Batteries are rated in terms of ampere - hours (A ⋅ h). For example,
a battery that can deliver a current of 3.0 A for 5.0 h is rated
at 15 A ? h. (a) What is the total energy, in kilowatt - hours, stored
in a 12 - V battery rated at 55 A ⋅ h? (b) At $0.12 per kilowatthour,
what is the value of the electricity that can be produced
by this battery?
