A certain situation requires that either 160 or 75 W be supplied to a 48 V battery
from a 120 V rms 60 Hz ac source. There is a two-position switch on a control
panel set at either 160 or 75. Design a single circuit to deliver both values of
power, and specify what the control switch will do. Specify the values of all the
components in your circuit. The internal resistance of the battery is 0.1 .
