Electronics - Resistance and Power
Exercise : Resistance and Power - True or False
A 12-volt battery is delivering 3 amperes to a resistor. The power dissipated by the resistor is 4 watts.
Resistance limits the flow of current.
If 500 mA is flowing through a 10 resistor, the wattage rating of the resistor should be 2 watts.
A digital voltmeter can be used to measure resistance.
Carbon composition resistors are the most common and the least expensive type of fixed-value resistor.
