ocr: TRANSFORMER - RANSFORMERS change the voltage ofan electricity STEP-DOWN - TRANSFORMER - supply. They consist oftwo coils wound onto an iron core. When an alternating voltage travels POWER LINE through the primary coil, it produces a changing magnetic fieldin the core. This induces an alternating voltage in the EE E EB L EE secondary coil. Depending on - EE - the relative numbers ofturns int the coils, the voltage will increase or decrease. IRON CORE PRIMARY COIL I 4 - STEP-UP TRANSFORMER GENERATOR - V SECONDARY COIL Vh 1
