Calculating Resistance and Current in a Light Bulb Circuit

1. There is a current of 0.80 A through a light bulb in a
10 V circuit. What is the resistance of this light bulb?
2. A 40 watts light bulb is connected to a 110.0 V
electric outlet. (a) What current flows through the bulb? (b) What is the
resistance of the bulb?
