If a circuit has a 24V battery and two resistors of 6Ω and 12Ω in series, what is the voltage across the 12Ω resistor?

If a circuit has a 24V battery and two resistors of 6Ω and 12Ω in series, what is the voltage across the 12Ω resistor?

Step 1: Identify the total voltage from the battery, which is 24V.
Step 2: Identify the resistors in the circuit. We have R1 = 6Ω and R2 = 12Ω.
Step 3: Calculate the total resistance in the circuit by adding the two resistors together: Rtotal = R1 + R2 = 6Ω + 12Ω = 18Ω.
Step 4: Use the voltage divider rule to find the voltage across the 12Ω resistor (R2). The formula is V2 = (R2 / Rtotal) * Vtotal.
Step 5: Substitute the values into the formula: V2 = (12Ω / 18Ω) * 24V.
Step 6: Simplify the fraction: 12 / 18 = 2 / 3.
Step 7: Multiply by the total voltage: V2 = (2 / 3) * 24V = 16V.
Step 8: Conclude that the voltage across the 12Ω resistor is 16V.

Voltage Divider Rule – The voltage divider rule is used to determine the voltage drop across a resistor in a series circuit based on the resistance values and the total voltage.
Series Circuit – In a series circuit, the total voltage is divided among the resistors, and the same current flows through each resistor.
Ohm's Law – Ohm's Law relates voltage, current, and resistance in an electrical circuit, stating that V = I * R.
