What is the rms current delivered to the transformer

Reference no: EM13488890

An AC adapter for a laptop computer unit uses a transformer to reduce the line voltage of 110 V (rms) to a voltage of 18.5 V. The rms current delivered to the laptop is 4.6 A (max). What is the rms current delivered to the transformer if the transformer is only 52% efficient?
