Answer 2

Calculation of Voltage across the Second Resistor

To calculate the voltage across the second resistor, we need to apply Ohm's Law, which states that the voltage across a resistor is equal to the current flowing through it multiplied by its resistance.

In this case, the two resistors are connected in series, which means that the same current flows through both resistors. Therefore, we can use the formula:

V = I * R

where: - V is the voltage across the resistor, - I is the current flowing through the resistor, and - R is the resistance of the resistor.

Given that the resistance of the first resistor is 3 Ω and the resistance of the second resistor is 5 Ω, and the voltage across the first resistor is 6 V, we can calculate the current flowing through the circuit.

Calculation Steps:

1. Calculate the current flowing through the circuit using Ohm's Law: - Current (I) = Voltage (V) / Resistance (R) - Current (I) = 6 V / 3 Ω - Current (I) = 2 A

2. Calculate the voltage across the second resistor using Ohm's Law: - Voltage (V) = Current (I) * Resistance (R) - Voltage (V) = 2 A * 5 Ω - Voltage (V) = 10 V

Therefore, the voltage across the second resistor is 10 V.

Please note that the calculations provided above are based on the given information and assumptions.
