Formula: **Parallel Circuit of Resistors**

$$U ~=~ U_1 ~=~ U_2 ~=~ U_3 ~=~ ...$$
$$U ~=~ U_1 ~=~ U_2 ~=~ U_3 ~=~ ...$$

## 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...
