Three identical light bulbs are connected to two batteries as shown in the diagram above. through a wire, a bulb, or a battery (not through the air). How many valid energy conservation (loop) equations is it possible to write for this circuit connecting wires is small enough to neglect. $$\begin{array}{l}+2^{?}\mathrm{emf}?E_{2}L?E_{3}L=0\\ +E_{2}L?E_{3}L?0\\ +2^{\times }emf?E_{1}L?E_{2}L=0\\ E_{1}L?E_{2}L=0\\ +2^{\times }emf?E_{1}L?E_{2}L?E_{3}L=0\\ +2^{\times }emf?E_{1}L?E_{3}L=0\\ E_{1}L?E_{3}L=0\end{array}$$ valid charge conservation equations for this circuit? $$\begin{array}{l}{i}_1=i_2\\ i_1=i_3\\ i_1=i_2+i_3\end{array}$$ Tungsten has $$6\mathrm{e}+28$$ mobile electrons per cubic meter. electric field magnitudes: What is the magnitude of the electric field inside bulb \# 1 ? $$E_1=\mathrm{V}/\mathrm{m}$$ What is the magnitude of the electric field inside bulb \#2? $$E_2=\mathrm{V}/\mathrm{m}$$ How many electrons per second enter bulb \# 1 ? $$i_1=$$ electrons $$/\mathrm{s}$$ How many electrons per second enter bulb \#2? $$i_2=$$ electrons $$/\mathrm{s}$$
