Final answer:
The question involves calculating the current through each resistor in a series circuit after a switch is closed. Using Ohm's Law and the provided voltage and resistor values, the same current of 0.0464 A flows through all resistors.
Step-by-step explanation:
The question is regarding the current through resistors in a circuit after a switch is closed. Since the value of the resistors and the voltage is provided, we can apply Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). However, the given values for the resistors in the question do not match the provided reference, so it's likely there is a typo or misunderstanding. Assuming that r1, r2, r3, and r4 are all equal to 140Ω and we have a voltage (v) of 26.0V, and the resistors are connected in series, then we can calculate the total resistance (Rt) and use Ohm's Law (V = IR) to find the current flowing through the circuit.
First, calculate the total resistance:
Rt = r1 + r2 + r3 + r4
Rt = 140Ω + 140Ω + 140Ω + 140Ω
Rt = 560Ω
Then, apply Ohm's Law to find the current:
I = V / Rt
I = 26.0V / 560Ω
I = 0.0464 A
Thus, the same amount of current, 0.0464 A, flows through all of the resistors when the switch is closed, and the resistors are in series.
