All Formulas of ch 12 ( Electricity)

Dear student,
In the chapter electricity, the main numerical formulas are;
$$\begin{gathered} I =\frac{dq}{dt} (I =current, q=charge, and t=time) \\ V=IR (V= potential difference, R = resis\tan ce) \\ P =VI (P=power) \\ E = Pt =VIt (E =electrical energy spent) \\ Equivalent resis\tan ce in series; \\ R=R_1+R_2 \\ Equivalent resis\tan ce in paralle, \\ \frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2} \end{gathered}$$
