Electrical Circuits Resistance R0 (a combination of resistances R1 and R2) in a parallel connection can be determined as follows:
From the above, the total current I flowing in this circuit can be determined from Ohm's law as follows:
The total current I is also equal to the sum of currents I1 and I2 flowing through individual resistances R1 and R2
Since battery voltage V is applied equally to all resistances, the strength of currents I1 and I2 can be determined from Ohm's law as follows:
