Calculate Power of the Lamp

What is the given data?

A current of 0.8 A passes through a lamp with a resistance of 5 Ohms.

What is the question?

What is the power supplied to the lamp in Watts?

Answer:

The power supplied to the lamp can be calculated using the formula P = I^2 R, where P is power, I is current, and R is resistance.

Given data:

Current (I) = 0.8 A

Resistance (R) = 5 Ohms

Now, we can substitute the values into the formula:

Power (P) = Current^2 x Resistance

Power (P) = 0.8^2 x 5

Power (P) = 0.64 x 5

Power (P) = 3.2 Watts

Therefore, the power supplied to the lamp is 3.2 Watts.
