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.
