Consider a transformer as pictured below. The transformer consists of two coils wound around a common ferromagnetic iron core. The input end of the transformer has N₁ = 42 turns, while the output end of the transformer has N₂ = 68 turns. Ferromagnetic Iron Core Voltage In: V₁ Current In: I, -N₁ Coils N, N₂ Coils- Voltage Out: V₂ Current Out: 1₂ Is this a step up or step down transformer? Step Up Transformer An amount of data was collected for this transformer for various input powers. The input voltage V₁ input current I₁ and output current I₂ are measured and presented in the table below. Complete the table by calculating the input power P₁ (In WATTS), the output voltage V₂ and the output power P₂. It is a good idea to hit the 'check' button as you go to make sure you aren't making a mistake
