1. Homework Statement
You have a circuit with a single resistor of resistance R connected to a battery that has zero internal resistance and has a power output of 12W. A resistor of resistance of 6R is now connected in parallel to the original resistor. How much power is now dissipated in the...
There are some classes that are not offered at my university, which I want to self study.
How can I self study them effectively to get the same benefit as doing the class at university?
There is this class MIT 6.024j Mathematics for Computer Science which I very much want to take online...
