voltage = 5 V, resistance = 20 Ω: [___] A

voltage = 5 V, resistance = 20 Ω: [___] A

Examine Table B then read the statement and choose the best responses. As the resistance increased under 25 V, the current . Compared to calculated currents, experimental currents proved to be . Currents varied proportionally according to resistance: 10 Ω of resistance produced a current of A, while 100 Ω of resistance produced a current of A.
