Hard Stuff
Can anyone explain to me what Newtons 2nd law means?

Newton's second law means exactly what it says: If a moving object has absolutely no forces acting on it then it will continue to move in a straight line at constant velocity".
The formula for calculating total resistance in a parallel circuit is 1/RT = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn, where RT is the total resistance and R1, R2, R3, etc. are the individual resistances.
The total current in a parallel circuit is equal to the sum of the individual branch currents. This can be calculated by using the formula IT = I1 + I2 + I3 + ... + In, where IT is the total current and I1, I2, I3, etc. are the individual branch currents.
In a series circuit, the components are connected one after another, creating a single path for the current to flow. In a parallel circuit, the components are connected in multiple branches, allowing the current to flow through different paths.
The voltage in a parallel circuit is the same across all branches and is equal to the source voltage. This means that the voltage can be calculated using the formula VR = VS, where VR is the voltage in the circuit and VS is the source voltage.
Kirchhoff's current law states that the sum of the currents entering a node must equal the sum of the currents leaving the node. In a parallel circuit, this means that the total current entering the node must be equal to the sum of the individual branch currents leaving the node.
