With no load attached, the voltage at the terminals of a particular power supply is 50.8 V. When a 10-W load is attached, the voltage drops to 49 V.
a. Determine vS and RS for this non ideal source.
b. What voltage would be measured at the terminals in the presence of a 15-? load resistor?
c. How much current could be drawn from this power supply under short-circuit conditions?
Known quantities:
Open-circuit voltage at the terminals of the power source is 50.8 V; voltage drop with a 10-W load attached is 49 V.
Find:
a) The voltage and the internal resistance of the source
b) The voltage at its terminals with a 15-? load resistor attached
c) The current that can be derived from the source under short-circuit conditions.
