multipleQuestions newQuestion 2. A series circuit has a 9V battery connected to two resistors, R1 = 3Ω and R2= 6Ω. What is the current flowing through the circuit? newAnswer The current flowing through the circuit is 1A. Steps: 1. Calculate the total resistance (R_total) in the series circuit: In a series circuit, the total resistance is the sum of individual resistances. R_total = R1 + R2 R_total = 3Ω + 6Ω R_total = 9Ω 2. Apply Ohm's Law to find the current (I): Ohm's Law states V = I * R_total, so I = V / R_total. I = 9V / 9Ω I = 1A newQuestion 3. In a series circuit, the current is 2A, and the total voltage supplied is 12V. If R1 = 4Ω, what is the newAnswer This question is incomplete. However, based on the provided information, we can calculate the total resistance of the circuit. Steps to calculate total resistance: 1. Apply Ohm's Law to find the total resistance (R_total): Ohm's Law states V_total = I * R_total, so R_total = V_total / I. R_total = 12V / 2A R_total = 6Ω If the question intended to ask for the value of a second resistor (R2), it would be: R_total = R1 + R2 6Ω = 4Ω + R2 R2 = 6Ω - 4Ω R2 = 2Ω
