Round your answer to two decimal places.
-According to Ohm's law, the electric current I, in amperes, in a circuit varies directly as the voltage V. When 25 volts are applied, the current is 4 amperes. What is the current when 7 volts are
Applied?
A) 1.12 amperes
B) 6.25 amperes
C) 43.75 amperes
D) 36 amperes

Ohm's law states that I = V/R, where I is the current, V is the voltage, and R is the resistance. Given that 25 volts produce 4 amperes, we can find the resistance (R = V/I = 25/4 ohms). To find the current at 7 volts, use I = V/R = 7/(25/4) = 1.12 amperes.
