A heater with a resistance of 100 is connected to a current source with an EMF of 48 V and
an internal resistance of 1.5 . Find the current power on the heater.
Current power on the heater is
where I - current through the heater;
R - resistance of heater.
Current through the heater is
where E - EMF of the current source;
Rint - its internal resistance.
So,
Answer: 22.36 W
