Question

Three resistances 12 ohms each are connected in parallel. Three such combinations are connected in series. What is the total resistance?​

Answer 1

Resistance of three resistors in parallel

1/R = 1/12 + 1/12 + 1/12 + 1/12

1/R = 4/12

1/R = 1/3

R = 3 ohms

Three such combinations are connected in series

Total resistance = 3 + 3 + 3 = 9 ohms

So total resistance of the combination is 9 ohms.

Answer 2

Explanation:

In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed....
