Given a parallel circuit with an equivalent resistance of 6 ohms, what is the total circuit current with a 48-volt source?

To find the total circuit current in a parallel circuit, Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), is applied. Here, the equivalent resistance of the circuit is given as 6 ohms, and the voltage from the source is 48 volts.

Using the formula:

I = V / R

we substitute the known values:

I = 48 volts / 6 ohms

I = 8 A

This calculation shows that the total current flowing through the circuit is 8 amperes. It illustrates how the relationship between voltage and resistance directly determines the current in an electrical system.
