Let's say that I have a circuit consisting of a power supply of $220V$ and $2$ bulbs of power-voltage rating $40W-220V$ and $60W-220V$ in series. How would I calculate the current flowing across the circuit? I know how to calculate it if there is a single bulb (Using $P = I^2 * R$, $P = V^2/R$ and $P = VI$), but I'm confused about the use of the formulae for multiple bulbs/appliances.

Thank you
