If a 12V battery supplies an electric current of 13A, how do I work a the power supplied?

resistance = R = E/I = 12v/13A
Then Power = P = I2R

To find the power supplied by a 12V battery with an electric current of 13A, you need to use the formulas for resistance (R) and power (P).

First, calculate the resistance using Ohm's Law formula: R = E/I, where E is the voltage (12V) and I is the current (13A). Plug in the values to find the resistance: R = 12V / 13A.

Next, use the formula for power: P = I^2 * R, where I is the current and R is the resistance. Plug in the values you calculated earlier: P = (13A)^2 * (12V / 13A).

Simplifying this expression, you can cancel out the unit of ampere (A) from the numerator and denominator, leaving you with: P = 13A * 12V.

Multiply the values: P = 156V*A.

Therefore, the power supplied by the battery is 156 watts (W).

Regarding the topic of consumer and energy, it seems like you want to understand the relationship between the two. In general, a consumer is any device or system that uses energy to perform a task. Energy, on the other hand, is the ability to do work or cause change.

When consumers use energy, the energy is converted from one form to another. For example, when you use a light bulb, electrical energy is converted into light and heat energy. Similarly, when you use a microwave, electrical energy is converted into heat energy to cook food.

By understanding how consumers convert energy, you can also learn about the efficiency of different devices and systems. Energy efficiency refers to how effectively a consumer converts the input energy into useful output energy. High energy efficiency means less energy is wasted as heat or other forms and more energy is used for the intended purpose.

To study this topic further, you might want to explore concepts such as energy conservation, different types of energy sources (e.g., renewable vs. non-renewable), and the impact of consumer behavior on energy usage and environmental sustainability.
