Explain the relationship between watts, amps, volts, and ohms in electrical circuits.

• Ohms are a measure of power consumption in circuits

• Amps are directly proportional to volts in electrical circuits

• The relationship between watts, amps, volts, and ohms in electrical circuits is defined by the formulas: W = V * I and V = I * R.

• The relationship between watts and ohms is defined by the formula W = R^2

What is the difference between analog and digital audio signals?
