Answer 2

Determining the Nominal Resistance of an 80W, 220V Lamp

To determine the nominal resistance of a lamp, we can use the formula P = U^2 / R, where P is the power in watts, U is the voltage in volts, and R is the resistance in ohms. Let's calculate the nominal resistance of the 80W, 220V lamp using this formula.

The formula can be rearranged to solve for resistance:

R = U^2 / P

Substituting the given values: - Power (P) = 80W - Voltage (U) = 220V

We can calculate the nominal resistance using the given formula.

R = U^2 / P

R = 220^2 / 80

R = 48400 / 80

R = 605 ohms

So, the nominal resistance of the 80W, 220V lamp is 605 ohms.
