Find the current is in the circuit?

i = 1.2 [amp].

Explanation:

In order to find the current in the circuit, we must perform a sum of voltages equal to zero, around the mesh.

∑V = 0

Let's take the direction of the current as shown in the drawing Clockwise.

Note: The negative sign means that the current moves in a counterclockwise direction.

  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
