Question

Resistors having resistances of 15 02, 20 Q and 10$ are connected in
Solved examples of resisters in parallel
parallel. What is the effective resistance in the circuit?​

Answer 1

Answer:

Effective resistance when R1, R2, and R3 connected in parallel,

1/R=1/R1+1/R2+1/R3

1/R=1/15+1/20+1/10

1/R =(20+15+30)/300

1/R=65/300

R=300/65

R=4.61 Ohms
