The electrical power converted into heat when an alternating current passes through an ohmic resistance can be calculated using the formula P=I^2R, where P is the power in watts, I is the current in amperes, and R is the resistance in ohms.

Explanation:

Ohmic resistance is a type of resistance that behaves in a linear manner with respect to the applied voltage. When an alternating current (AC) passes through an ohmic resistance, the current and voltage alternate in direction at a certain frequency, causing the resistance to dissipate electrical energy in the form of heat.

The amount of electrical power converted into heat is determined by the resistance of the material and the amount of current passing through it. The power loss due to resistance is proportional to the square of the current passing through the material, as described by Joule's law.

Joule's law states that the heat generated by a resistor is directly proportional to the square of the current passing through it, and is given by the equation P=I^2R, where P is the power in watts, I is the current in amperes, and R is the resistance in ohms.

The power loss due to resistance can be a significant factor in the design and operation of electrical circuits, as it can result in the heating of components and can cause damage or failure if not properly managed.

In summary, when an alternating current passes through an ohmic resistance, the electrical power converted into heat is determined by the resistance of the material and the amount of current passing through it, and is given by the equation P=I^2R.
