The ignition circuit of an automobile is powered by a 12-V battery. How are we able generate large voltages with this power source?
The equation P= V2/R indicates that the power dissipatedin a resistor decreases if the resistance is increased, whereasthe equation P=I2R implies the opposite. Is there acontradiction here? Explain.
Imagine a hypothetical universe where Ohm's law still holds true, but the nature of matter allows for electrical resistors to possess negative resistance values. In such a universe, how would the rules for combining resistors in series and parallel change?
