## Homework Statement

How do i find the equivalent voltage source of...

1) Two AC voltage sources in series with same frequency and phase = ?

2) One AC voltage source in series with a DC voltage source = ?

## Homework Equations

Equation of a AC voltage source as a function of time [tex]V(t)=V_m * sin( \omega *t + \theta )[/tex]

## The Attempt at a Solution

1) [tex]V(t)=(V_{m_1}+V_{m_2}) * sin( \omega *t + \theta )[/tex]

2) [tex]V(t)=(V_{DC}+V_m) * sin( \omega *t + \theta )[/tex]
