Ohm's Law
Power supplies differ from batteries in that
If voltage across a resistance doubles
The efficiency rating of a power supply is determined by internal power loss.
Heat produced by a resistor is generally a desirable effect.
Doubling the voltage across a resistor will cut the current by half.
The current through a resistor can be found by dividing the resistor's voltage by its ohmic value.
If the current in the given circuit is increased to 24 mA, the source voltage must have tripled.
Generally, increasing the resistance in a circuit will decrease the current.
The voltage drop across a resistor is simply a difference of potential across that resistor.
Power is a measure of how fast current is flowing.
