Acurrent of 12 amps is measured in a circuit with a total resistance of 9.0 ohms. what is the size of the voltage source that supplies this circuit? a. 108 volts b. 21 volts c. 1.3 volts d. 0.75 volts

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
