A transformer consists of 275 primary windings and 834 secondary windings. If the potential difference across the primary coil is 25.0 V. what is the voltage across the secondary coil? Is this a step up or step down transformer? Explain. What is the effective load resistance of the secondary coil if it is connected across a 125 Ω resistor ?
