Calculating Current in a Circuit with a Battery and a Light Bulb

To calculate the current in a circuit with a battery and a light bulb, we can use Ohm's law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) between them. The formula for Ohm's law is:

I = V / R

Where: - I = current in amperes (A) - V = voltage in volts (V) - R = resistance in ohms (Ω)

In this case, the electromotive force (EMF) of the battery (also known as the voltage) is 12 volts, and the internal resistance of the battery is 0.01 ohms. The resistance of the light bulb is 10 ohms.

Using Ohm's law, we can calculate the current flowing through the circuit.

Calculating Current

The total resistance in the circuit is the sum of the internal resistance of the battery and the resistance of the light bulb:

Total Resistance (R_total) = Internal Resistance + Resistance of Light Bulb R_total = 0.01 Ω + 10 Ω R_total = 10.01 Ω

Now, we can use Ohm's law to calculate the current:

I = V / R I = 12 V / 10.01 Ω I ≈ 1.1988 A

So, the current flowing through the circuit when the 12-volt battery with an internal resistance of 0.01 ohms is connected to a 10-ohm light bulb is approximately 1.1988 amperes.
