Hello, I'm an expert in electrical engineering and I'm here to help you understand the relationship between volts, amps, and watts. Let's dive into the concept first.

Electricity is a form of energy that flows through conductors like wires. The flow of electricity is measured in amps (amperes), which is a unit of electric current. The pressure that pushes the current through the conductor is called voltage, and it is measured in volts. The power that the current delivers is measured in watts.

When you ask, "How many amps are in 12 volts?" you're asking about the current that would flow through a circuit with a voltage of 12 volts. However, the amount of current (amps) is not solely determined by the voltage (volts). It also depends on the resistance in the circuit. Ohm's Law, which is \( V = IR \) (where \( V \) is voltage, \( I \) is current, and \( R \) is resistance), shows the relationship between these three quantities.

If you have a circuit with a fixed voltage of 12 volts and you want to know the current (amps), you need to know the resistance (ohms) of the circuit. The current can be calculated using the formula \( I = \frac{V}{R} \). Without knowing the resistance, we cannot determine the exact current.

Now, let's address the example provided: "12 watts/12 volts = 1 amp." This equation is actually showing how to calculate the current if you know the power (watts) and the voltage. The formula used here is \( P = VI \) (where \( P \) is power in watts, \( V \) is voltage in volts, and \( I \) is current in amps). If you rearrange this formula to solve for current, you get \( I = \frac{P}{V} \). So, if a device has a power rating of 12 watts and operates at 12 volts, it would indeed draw 1 amp of current.

For the conversion of amps to watts, the equation is correct: Watts = Amps x Volts. If you have a current of 1 amp flowing through a 110-volt circuit, the power consumption would be 110 watts.

In summary, to find out how many amps are in 12 volts, you need to know the resistance of the circuit. The example given is a specific case where the power and voltage are known, allowing us to calculate the current. And the conversion between amps and watts is a straightforward multiplication when the voltage is constant.
