Determine the ideal voltage source
needed for the resistors connected in series.
Answer:
An ideal voltage source of
12 volts
is needed for the three resistors connected in series to generate a required current of 0.5A in the circuit.
Explanation:
First, you need to calculate the total resistance of the circuit (R_total) using Ohm's Law:
R_total = R1 + R2 + R3
R_total = 6 ohms + 8 ohms + 10 ohms
R_total = 24 ohms
Next, calculate the voltage needed using Ohm's Law again:
V = I * R_total
V = 0.5A * 24 ohms
V = 12 volts
==============================
How is it done?
When faced with similar questions involving resistors connected in series, you can use the same approach to determine the ideal voltage source needed.
- Calculate the total resistance (R_total) by adding up the individual resistances of the resistors in series.
- R_total = R1 + R2 + R3 + ...
- Calculate the voltage needed using Ohm's Law
- V = I * R_total
Conclusion!
By following these steps, you can determine the ideal voltage source needed to generate a specific current in a circuit with resistors connected in series. This approach can be applied to any similar question involving resistors in series.
