Question

with the help of a diagram derive the formula for equivalent
resistance for three resistances connected in parallel

Fuad · Answer

IR=IR1+ IR2​+IR3
V/R=V/R1+V/R2+V/R3
V/R=V[1/R1+1/R2+1/R3]
V/VR=[1/R1+1/R2+1/R3]
1/RP=R1R2+R2R3+R1R3/R1R2R3

RP=R1R2R3/R1R2+R2R3+R1R3
 =Product of resistors/Sum of resistors
