What is the current flow in a series circuit with three resistors rated at 5 ohms, 10 ohms, and 15 ohms, and a circuit voltage of 240 volts?

• A. 4 amps
• B. 6 amps
• C. 8 amps
• D. 10 amps

Answer: (C)

To determine the current flow in a series circuit, you first need to find the total resistance. In a series circuit, the total resistance is simply the sum of the individual resistances. Here, you have three resistors with values of 5 ohms, 10 ohms, and 15 ohms. Calculating the total resistance: \[ Total\ Resistance = 5\ ohms + 10\ ohms + 15\ ohms = 30\ ohms \] Once you have the total resistance, you can apply Ohm's Law, which states: \[ I = \frac{V}{R} \] Where \(I\) is the current, \(V\) is the voltage, and \(R\) is the total resistance. Given that the circuit voltage is 240 volts, you can now calculate the current: \[ I = \frac{240\ volts}{30\ ohms} = 8\ amps \] This calculation shows that the current flowing through the circuit is 8 amps. This is why the correct answer is the option that corresponds to 8 amps.

Calculating the total resistance:

[

Total\ Resistance = 5\ ohms + 10\ ohms + 15\ ohms = 30\ ohms

]

Once you have the total resistance, you can apply Ohm's Law, which states:

[

I = \frac{V}{R}

]

Where (I) is the current, (V) is the voltage, and (R) is the total resistance. Given that the circuit voltage is 240 volts, you can now calculate the current:

[

I = \frac{240\ volts}{30\ ohms} = 8\ amps

]

This calculation shows that the current flowing through the circuit is 8 amps. This is why the correct answer is the option that corresponds to 8 amps.
