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.
You have to clean and tighten your battery terminals on a regular basis. Otherwise, they''ll drain your car battery.
