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)
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.
