Question
measurements of two electric currents are shown in the chart. which best compares the two currents? current x has a greater potential difference, and the charges flow at a slower rate. current y has a greater potential difference, and the charges flow at a slower rate. current x has a greater potential difference, and the charges flow at a faster rate current y has a greater potential difference, and the charges flow at a faster rate
Volts measure potential difference; higher volts mean greater potential difference. Amperes measure current (charge flow rate); higher amperes mean faster flow. Current X has 15 volts (greater than Y's 9 volts) and 7.8 amperes (faster than Y's 0.5 amperes).
