Formula: Parallel Circuit of Resistors

Parallel connection of three resistors - Voltages

Voltage

Unit
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

Unit
  • \(U=U_1\) 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...
