Current |
We define voltage as the amount of potential energy between two points on a circuit. One point has more charge than another. This difference in charge between the two points is called voltage.
|
Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current).

Resistance |
Power |
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). ... Insulators: Materials that present high resistance and restrict the flow of electrons.
|
Power is the rate with respect to time at which work is done; it is the time derivative of work. If a constant force F is applied throughout a distance x.

Parallel Circuit |
Series Circuit |
a circuit in which the electric current passes through two or more branches or connected parts at the same time before it combines again.
|
A series circuit comprises a path along which the whole current flows through each component. A parallel circuit comprises branches so that the current divides and only part of it flows through any branch.

Ohm's Law |
Kirchhoff's law |
Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R.
|
Kirchhoff's laws quantify how current flows through a circuit and how voltage varies around a loop in a circuit. Kirchhoff's current law (1st Law) states that the current flowing into a node (or a junction) must be equal to the current flowing out of it. This is a consequence of charge conservation.

Strengths A strength during this project was being self paced since I worked independently during this project. I feel the creativity and exploration was expanded because I worked independently.
|
Challenges A challenge for me was not having a second set of hands or opinion that would of guided me to not stress so much about the project. Another challenge was building codes since it was the first time I tried something like this and I had no personal background on circuits.
