Construct the circuit in Figure 1 in the Circuit JS simulator. Note that the voltage source is given in RMS. Within Circuit JS while defining the max voltage of the voltage source include “rms” after the number to tell Circuit JS that this is a rms value. Also note that there are additional parameters when instantiating a transformer in Circuit JS. Leave these at the default values. Additionally, transformers may have problems simulating in Circuit JS.  Answer the following: 1. From the simulation results, determine the power dissipated in R2 and compare to the expected value from the previous section.2. Change the transformer ratio (“Ratio” as a fraction when you “Edit…” the transformer component) to the value calculated in the previous section to provide maximum power transfer in R2. Note: In Circuit JS, Transformer Ratio = Primary/Secondary.3. Rerun the simulation, calculate the power dissipated in R2 and compare to the expected value from the previous section.4. Change the…

A 1,000/200 V transformer takes 0.3 at p.f. of 0.2 on open circuit. Find the magnetising, and iron loss component of no- load primary current.

a single-phase transformer serves a 7.2kw resistive loadlocated 200 ft from the transformer. each conductor from the transformer to load has an impedence of (0.78+j0.052) ohms per 1000ft. if the voltage at the load terminal is 240v, the magnitude of the voltage (v)  at the transformer secondary is most nearly:
