Question

Contrast series and parallel circuits in terms of what they look like and how they calculate Equivalent resistance

Answer 1

Let's see

For series connection

`\\ \rm\Rrightarrow R_(eq)=R_1+R_2+R_3\dots`

For parallel connection

`\\ \rm\Rrightarrow (1)/(R_(eq))=(1)/(R_1)+(1)/(R_2)+(1)/(R_3)\dots`

Answer 2

In a series circuit the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component.

In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
