Parallel DC circuit include as many parallel lines as desired.
1. In a parallel circuit, voltage is the same throughout each parallel leg, no matter how many legs are added.
Vs = V1 = V2 = V3
2. Current through a parallel circuit is the sum of the current in each leg.
IT = I1 + I2 + I3
3. Resistance total calculation as follows:
RT = 1 / ( 1/R1 + 1/R2 + 1/R3 )
Example : Parallel DC circuit Analysis :
Current Divider
The current divider is mostly used to determine the current on a parallel resistor circuit with only two brances.
Example :
Formula :
IRX = IT ( RT / RX )
