Secondary coil:
Voltage =
Current =
Explanation:
The transformer equation:
Therefore, we have
Overall power remains constant, although it wouldn't actually, energy would be lost as heat, but forget about that for this.
a). A step up transformer will increase the voltage connected in its input side and present it at the output.
Step up factor
and
Output Voltage
#="Step up factor"xx"Input Voltage"#
For the given transformer
Step up factor
Voltage produced in the secondary circuit
b). Ignoring resistive losses and losses due to eddy currents
Input Power
#=# Output Power
Input Voltage
Output Voltage
