Voltage

Explanation:

A step-up transfomer will increase the voltage produced by a current, as transformers may alter the induced #"emf"# or "voltage" in a circuit. The secondary coil has more turns than the primary turns on the transformer, and so the voltage becomes greater. This is given by the equation:

#V_p/V_s=N_p/N_s#

where:

  • #V_p,V_s# are the primary and secondary voltages

  • #N_p.N_s# are the primary number of coil turns and the secondary number of coil turns on a transformer
