... Conclusion: Transmitting power with higher voltages and lower currents decreases power losses. But this requires transforming generated power to high voltages and then transforming back down to lower voltages for use in homes and industries. This makes AC power very practical, as transformers use AC ...

... A component where the current is directly proportional to the voltage is said to obey Ohm’s Law and is called ohmic. This means: 1. A graph of V vs. I is a straight line through the origin. 2. V = I × R where R is constant whatever the value of the current or voltage. Note that the definition of res ...
