Convert AC voltages using electromagnetic induction
Changing magnetic field required; DC field is constant
Equivalent DC voltage/current delivering same power
V_{ ext{rms}} = rac{V_{ ext{peak}}}{sqrt{2}}
230V RMS at 50 Hz
VSVP=NSNP\frac{V_S}{V_P} = \frac{N_S}{N_P}VPVS=NPNS
NS>NPN_S > N_PNS>NP (more secondary turns)
Increases current (IS>IPI_S > I_PIS>IP)
Lower current reduces loss (Ploss=I2RP_{\text{loss}} = I^2RPloss=I2R)
Reduces eddy currents in transformer
