A circuit with a source of 120 volts is connected across four parallel 60 ohms resistors. The current through each resistor is:

To determine the current through each resistor in a parallel circuit, it’s important to understand how the total voltage across the resistors is distributed and how current behaves in parallel circuits. In this scenario, each of the four resistors has the same resistance value of 60 ohms, and they are all connected to a 120-volt source.

Using Ohm's Law, which states that Voltage (V) = Current (I) × Resistance (R), we can rearrange this formula to find the current:

[ I = \frac{V}{R} ]

Given that the voltage across each resistor is the same, which is 120 volts, we can substitute this into the equation along with the resistance of 60 ohms:

[ I = \frac{120 , \text{volts}}{60 , \text{ohms}} ]

Calculating this gives:

[ I = 2 , \text{amps} ]

This calculation indicates that the current through each individual resistor in the parallel circuit is 2 amps. Therefore, the correct choice is the one indicating that the current through each resistor is 2 amps.

In the context of parallel circuits, it's important to remember that while the voltage
