b. If a 12V battery is connected to a series circuit with two resistors of 5Ω and 8Ω, calculate the total current flowing through the circuit.

1 answer

To calculate the total current flowing through the circuit, we need to use Ohm's Law. Ohm's Law states that current (I) is equal to voltage (V) divided by resistance (R), or I = V/R.

In this case, we have a 12V battery connected to a series circuit with two resistors of 5Ω and 8Ω. To find the total resistance (R_total) of the circuit, we add the individual resistances together: R_total = 5Ω + 8Ω = 13Ω.

Now that we have both the voltage (V = 12V) and the total resistance (R_total = 13Ω), we can calculate the total current (I) using Ohm's Law: I = V/R_total = 12V / 13Ω = 0.92A.

Therefore, the total current flowing through the circuit is 0.92A.
