If there are 3 resistors of 4 ohms, 6 ohms, and 12 ohms connected in series then what is the equivalent resistance?

If there are 3 resistors of 2 ohms, 2 ohms, and 1 ohm connected in parallel then what is the equivalent resistance?

think its the third option

need to see circuit to get time constant

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
