Hi, I need a hand please. Describe how you would use principles of series circuit to analyze a parallel circuit. What formulas used in a series circuit analysis would not apply?

The principles of a series circuit that can be used to analyze a parallel circuit is that of calculating total resistance in the circuits.

The formula used in a series circuit analysis for finding total resistance is different from that used in a parallel circuit for finding overall resistance. i.e.

For a series circuit total resistance Rt={R1+R2+R3+Rn}

For a parallel circuit, total resistance 1/Rt ={1/R1+1/R2+1/R3+1/Rn]

Explanation:

In a series circuit, the current passing through each component is the same where as in a parallel circuit the voltage through each component is the same.

The principles of series circuit that can be used to analyze a parallel circuit is that of calculating total resistance in the circuits. In a series circuit, total resistance is calculated as the sum of resistance of the components connected to the circuit, where as in a parallel circuit, overall resistance is the summation of the resistance of individual components.

This means you can use principles of series circuit to find total resistance then use that value to confirm the individual resistance values of components in a parallel circuits. This is possible because you will have the expected total resistance [calculated from the series circuit], then the sum of resistance of the same but individual components now in the parallel circuit should be equal to the total resistance calculated from the series circuit.

The formula for calculating resistance in series circuit given as :{Rt= R1+R2+R3+Rn} where Rt is the total resistance and R1,R2,R3...Rn are the values of individual components in the series circuit, can not be used in finding overall resistance in a parallel circuits because the formula for total resistance will change to : [1/Rt =1/R1+1/R2+1/R3+1/Rn]
