Ohm's Law
Ohm's Law states that the current flowing through an conductor between two points is proportional to the potential difference (V) between the two points.The relationship between the two will show an linear relationship (seen above). Where the increase of Current results in the increase in Voltage. Ohm's also states that resistance, will stay constant regardless of the change in current or voltage.
Resistance - opposition to the flow of electrons.
The formula purposed to represent this relationship is R= V/I
Kirchhoff's laws
Kirchhoff, a brilliant German physicist takes on Ohm's law and expands it into another concept within the circuit. The six laws he purposed presents the relationship in Current/Voltage/Resistance between all the loads in a single circuit. Parallel Circuits
The first law states that the total current (number of electrons) of a circuit equals to the sum of the current of all the loads.
1. It = I1 + I2 + I3 + .. In
The second law states that the voltage (potential difference) of all the loads within a circuit will equal to each other.
2. Vt = V1 = V2 = V3
The third law represents the relationship in resistance (opposition to electron flow) between the loads within a circuit.
3. 1/Rt = 1/R1 + 1/R2 + 1/Rn
Series Circuits
The first law in the series circuit states that the current measured in each load within a circuit will equal to each other.
1. It = I1= I2= I3= In
The second law states that the total voltage in a series circuit is the sum of the voltage of all the loads.
2. Vt = V1 + V2 + V3 + Vn
The third and final law states that the total resistance of a series circuit equals to the sum of all loads' resistance.
3. Rt = R1 + R2 + R3 + Rn
