If the measured resistance of a lamp is 45 ohms when it operates at a power of 80.0 watts, what is the current in the lamp?

Respuesta :

The current in the lamp will be 0.66 ampere. It is found by multiplying  the product of the resistance and square of the current. Its unit is the watt. It is the rate of the electric work done.

What is electric power?

Electric power is the product of the resistance and square of the current. Its unit is the watt. It is the rate of the electric work done.

The given data in the problem is;

The resistance is,R=45 ohms

The power is represented as;P=80.0 watts

The electric current is,I

The formula for the electric power is given as;

[tex]\rm P= I^2R \\\\ \rm 20= I^2 \times 45 \\\\ I=0.66 \ ampere[/tex]

Hence, the current in the lamp will be 0.66 ampere.
