Formula: Series Circuit of Resistors Electric current Currents
$$\class{red}{I} ~=~ \class{red}{I_1} ~=~ \class{red}{I_2} ~=~ \class{red}{I_3} ~=~ ... ~=~ \class{red}{I_n}$$
$$\class{red}{I} ~=~ \class{red}{I_1} ~=~ \class{red}{I_2} ~=~ \class{red}{I_3} ~=~ ... ~=~ \class{red}{I_n}$$
Electric current
$$ \class{red}{\boldsymbol I} $$ Unit $$ \mathrm{A} = \frac{ \mathrm C }{ \mathrm s } $$
Total current through the main wire of a series circuit of resistors.
For example, if the current is \( \class{red}{I_1} = 2 \, \mathrm{A} \), then it is also the current flowing through all other resistors and through the main wire: $$ \class{red}{I} ~=~ \class{red}{I_1} ~=~ \class{red}{I_2} ~=~ \class{red}{I_3} ~=~ 2 \, \mathrm{A} $$
Currents
$$ \class{red}{I_1}, \class{red}{I_2}, \class{red}{I_3},..., \class{red}{I_n} $$ Unit $$ \mathrm{A} $$- \(\class{red}{I_1}\) is the current flowing through the first resistor.
- \( \class{red}{I_2}\) is the current flowing through the second resistor.
- \( \class{red}{I_3}\) is the current flowing through the third resistor.
- And so on...
