103D Parallel Resistive Circuits Flashcards
1
Q
A circuit that has more than one path for current to flow is
A
Parallel circuit
2
Q
Parallel circuit formulas
A
ET = V1 = V2 = V3
RT = 1/(1/R1 + 1/R2 + 1/R3 + …. + 1/Rn)
IT = I1 + I2 + I3 + … + In
Total RT should be always smaller than the smallest ohms
3
Q
Kirchhoff’s Current Law states
A
All of the current values entering a junction point must equal all current values leaving the junction point
4
Q
What happens to the total resistance of a parallel circuit if one of the branches becomes open-circuited?
A
Increases
