Question

Three 3.0 ohm resistors are connected in parallel .What is the equivalent resistance?​

Answer 1

3/2 Ω

Step-by-step explanation:

ONE WAY :

1/ (1/3 + 1/3) = 1/(2/3) = 3/2 Ω

When you have two resistors in parallel , here is another way

3*3 /(3+3) = 9/6 = 3/2 Ω

( you can use this method ONLY when you have two parallel resitances !)
