Module 4 Electric Current-The Battery | Science 111
Key Takeaways Key Points. A simple circuit consists of a voltage source and a resistor. Ohm ''s law gives the relationship between current I, voltage V, and resistance R in a simple circuit: I = V/R.; The SI unit for measuring the rate of flow of electric charge is the ampere, which is equal to a charge flowing through some surface at the rate of one coulomb per second.
Ohm''s Law
For example, the voltage of a battery, which is stable over a long period, will be symbolized with a capital letter "E," while the voltage peak of a lightning strike at the very instant it hits a power line would most likely be symbolized with a lower-case letter "e" (or lower-case "v") to designate that value as being at a single ...
