Question

What is the ohms law and how would you apply it to find the amperage in this example 12 volts circuit and a load with 6 ohms of resistance we have a 50 watt bulb and a circuit with two amps flowing through it would a 12 volt automotive circuit be enough to light the bulb which law did you use

Answer 1

Ohm's Law, which states V = IR, allows us to determine that a 12V circuit with 6 ohms of resistance would have a current of 2.0A, sufficient to power a 50W bulb.

Step-by-step explanation:

Ohm's Law is fundamental in understanding the relationship between current, voltage, and resistance in an electrical circuit, which can be written as V = IR, where V is voltage, I is current, and R is resistance.

Given a 12-volt circuit and a load with 6 ohms of resistance, you can apply Ohm's Law to find the amperage by rearranging the equation to I = V/R. In this case, I = 12V / 6Ω, resulting in a current of 2.0A flowing through the circuit.

If we have a 50-watt bulb, we can find out if a 12-volt automotive circuit would be enough to light the bulb by comparing the power required by the bulb to the power available from the circuit.

The power (P) can also be calculated using the formula P = IV, which correlates to the bulb's requirements at the given voltage.

However, since we already know it requires 50W, a circuit capable of providing at least this power at 12V would suffice.
