In a given electric circuit, the current is directly proportional to the voltage. The current is 24 amperes when the voltage is 20 volts. Find the current for 30 volts.

Solution

Given the current is directly proportional to the voltage.

The current is 24 amperes when the voltage is 20 volts.

Need to find the current for 30 volts.

Now, the current is 24 amperes when the voltage is 20 volts.

Let the current is x amperes when the voltage is 30 volts.

By cross-multiplications,

20*x = 24*30

x = (24*30)/20

x = 36

Therefore, the current is 36 amperes for 30volts.
