Which statement is true? A. A resistor alters current and a switch turns current on and off B. A resistor measures voltage, and
a switch changes AC to DC or DC to AC C. A resistor alters current and a switch measures voltage D. A resistor changes AC to DC or DC to AC, and a switch turns current on and off
A. A resistor alters current and a switch turns current on and off
Explanation:
Resistor is the passive component that reduces the flow of current. Switch is the electrical device that turns on or off the current by closing and opening the electrical circuit.
Thus option A. A resistor alters current and a switch turns current on and off is correct.
