Solve.
-According to Ohmʹs law, the electric current, in amperes, in a circuit varies directly as the voltage. When 29 volts are applied, the current is 4 amperes. What is the current when 26 volts are applied?
A) 3.6 amperes
B) 59 amperes
C) 188.5 amperes
D) 7.3 amperes

We can set up a proportion using Ohm's law:

current / voltage = constant
4 / 29 = k

Solving for k, we get:

k = 4 / 29

Now we can use this constant to find the current when 26 volts are applied:

current / 26 = 4 / 29

Solving for current, we get:

current = (4 / 29) x 26 = 3.6 amperes
