Explanation:

Watts (W) is the unit of power in the International System of Units (SI). It measures the rate at which work is done or energy is transferred.

a) Amperes x volts: This is known as the product of current and voltage, which gives the power in watts. According to Ohm's law, power (P) is equal to the product of current (I) and voltage (V), so P = I * V. This equation shows that the product of amperes and volts is equivalent to watts.

b) Joules per second: The joule (J) is the unit of energy, and when divided by time (seconds), it gives power. So, joules per second is equivalent to watts. In other words, 1 watt is equal to 1 joule per second.

c) Amperes / volts: This expression represents the division of current by voltage. It does not correspond to the unit of power, as power is the product of current and voltage. Therefore, amperes divided by volts is not equivalent to watts.

d) (Amperes)2 x ohm: This expression represents the square of current multiplied by resistance. Although it involves current and resistance, it does not directly equate to power. The correct equation for power in terms of current and resistance is P = I^2 * R, where P is power, I is current, and R is resistance. Therefore, (amperes)2 multiplied by ohm is not equivalent to watts.

Conclusion:
Among the given options, amperes divided by volts (option c) is not equivalent to watts.
