Formula: Parallel Circuit of Resistors Voltage Individual voltages
$$U ~=~ U_1 ~=~ U_2 ~=~ U_3 ~=~ ...$$
$$U ~=~ U_1 ~=~ U_2 ~=~ U_3 ~=~ ...$$
Voltage
$$ U $$ Unit $$ \mathrm{V} = \frac{ \mathrm J }{ \mathrm C } = \frac{ \mathrm{kg} \, \mathrm{m}^2 }{ \mathrm{A} \, \mathrm{s}^3 } $$
Total (source) voltage of a parallel circuit of resistors.
For example, if a voltage \( U_1 = 200 \, \mathrm{V} \) is across the first resistor, then it is also the voltage across all resistors connected in parallel: $$ U ~=~ U_1 ~=~ U_2 ~=~U_3 ~=~ 200 \, \mathrm{A} $$
Individual voltages
$$ U_1, U_2, U_3, ... $$ Unit $$ \mathrm{V} $$- \(U=U_1\) is the voltage across the first resistor.
- \(U=U_2\) is the voltage across the second resistor.
- \(U=U_3\) is the voltage across the third resistor.
- And so on...
