Summary: Concepts of Ohm's Law, power, current, and voltage as they apply to simple circuits, series circuits, and parallel circuits are covered in these tutorials.
Ohm's Law -- Ohm's Law describes the fundamental relationship between voltage, resistance, and current. This Formula Solver! Series program shows the step-by-step solution for using any two values (which you can enter yourself) to find the third.
Current in a Simple Circuit -- Current is defined as the flow of electricity through a circuit over time. This Formula Solver! Series program shows the step-by-step solution for finding current, charge, or time from the other two values (which you can enter yourself).
Current in a Parallel Circuit -- Current is a function of voltage and resistance. This Formula Solver! Series program shows the step-by-step solution for finding current in parallel circuits using your own voltage and resistance values.
Power in a Simple Circuit -- In the world of electricity, power is the product of current and voltage. This Formula Solver! Series program shows the step-by-step solution for finding power, current, or voltage from the other two values (which you can enter yourself).
Power in a Parallel Circuit -- In parallel circuits, power is a function of current and voltage. This Formula Solver! Series program shows the step-by-step solution for using voltage and resistance to find current and power (all with your own values).
Resistance in a Series Circuit -- This Formula Solver! Series program shows the step-by-step solution for finding resistance in a series circuit (using up to four resistance values which you can enter yourself).
Resistance in a Parallel Circuit -- This Formula Solver! Series program shows the step-by-step solution for finding electrical resistance in parallel circuits (using up to four resistance values which you can enter yourself).
