So if the rheostat is turned to zero resistance the fan gets the full 0.2A.<BR><BR>If you turn the rheostat knob to make it 20 ohms, the total circuit resistance will be 20 + 60 = 80 ohms, the current ...
That is, as one resistor increases in value the other resistor is made to decrease in value--maintaining the total resistance the same--only the Ratio Changes. Like the Fixed Voltage Divider, the ...
