Question 1 5 pts 1 Details The electrical current, in amperes, in a circuit varies directly as the voltage. When 12 volts are applied, the current is 4 amperes. What is the current when 33 volts are applied? a) Give the General equation, using I for current, V for voltage, and k for the constant of proportionality. b) What is constant of proportionality? (Write as a reduced fraction) k = c) What is the mathematical model? (The specific formula involving I for current, V for voltage, and the constant of proportionality) d) What is the current when 33 volts are applied? amperes
