Question

Resistor having resistances of 15 ohm, 20 ohm, 10 ohm are connected in parallel. What is the effective resistance in the circuit?

Answer 1

Explanation:

since they are connected in parallel effective resistance is 60/13=4.6 Ohms

Answer 2

R= 15+20+10 =45 ohm

R/Rdash = 1/15+1/20+1/10 = 13/60

answer is 13/60
