Question

10. An automobile headlight has a resistance of 40 ohms when attached to a standard 12 volt battery. How much current flows through the headlight?

Answer 1

Using Ohm's Law with a voltage of 12 V and a resistance of 40 ohms, the current that flows through the headlight is found to be 0.3 A, or 300 milliamperes.

Step-by-step explanation:

To calculate the amount of current that flows through an automobile headlight with a resistance of 40 ohms when attached to a standard 12 volt battery, we use Ohm's Law, which is defined as I = V/R, where 'I' represents the current in amperes (A), 'V' is the voltage in volts (V), and 'R' is the resistance in ohms (Ω).

By substituting the known values into the formula:

I = 12 V / 40 Ω

We get:

I = 0.3 A

Therefore, the current flowing through the headlight is 0.3 amperes, or 300 milliamperes.

Answer 2

Current flows I = 0.3 Ampere

Step-by-step explanation:

Given:

Resistance = 40 ohms

Voltage = 12 volt

Find:

Current flows

Computation:

I = V / R

Current flows I = 12 / 40

Current flows I = 0.3 Ampere
