To find the current when 48 volts are applied, we can use the formula for direct variation:
I = kV
where I is the current, V is the voltage, and k is the constant of proportionality.
We can plug in the values given:
3 = k(12)
Solving for k:
k = 3/12
k = 1/4
Now that we have the value of k, we can find the current when 48 volts are applied:
I = (1/4)(48)
I = 12 amperes
Therefore, the current when 48 volts are applied is 12 amperes.
Answer the following prompt. Make sure to show all your work. According to Ohm’s Law, the electric current "I", in amperes, in a circuit varies directly as the voltage "V". When 12 volts are applied, the current is 3 amperes. What is the current when 48 volts are applied? (1 point)
