how is a transformer obeying ohm's law?

Question

unklerhaukus · Answer

A transformer has two coils of wire wrapped around an iron core. (primary and secondary) 
The power is conserved
The one on the coils has a higher the number of turns.
High voltages and low current can be converted into high currents and low current
The simple equation representing this
$$\frac{V_s}{V_p}=\frac{N_s}{N_p}=\frac{I_p}{I_s}$$
We can rearrange this to show
$${{V_pI_p}=V_sI_s}$$$$\quad P_p=P_s$$Power is conserved

We can also say that
individual side is obeying ohm's law while over-all power remain same.
As on one side the voltage increases while current decreases at the same ratio

Yes you are absolutely correct that individual sides are following ohm's law.Since the overall power is conserved.Current and Voltage change in ratio.Transformer do not transform power,but it transforms current or voltage as per the requirement.

When a load is connected to a transformer, the flow of current through the windings causes a voltage drop in accordance with Ohm's Law. This loss of voltage must be considered when designing transformers. Also the rise in temperature of transformer windings caused by losses will cause the resistance of the windings to increase which must also be taken into account when designing transformers.
