Question 405062: According to Ohm's law, the current, I, which measured in amperes, in an electrical circuit varies directly with the voltage, V. If the current is 0.64 ampere when the voltage is 24 volts, find the current when the voltage is 48 volts.

1.28 amperes (the voltage is doubled, so the current doubles as well). In case you're wondering, Ohm's law says I = V/R, which implies that the current is directly proportional to voltage.
