How many coulombs of electricity pass through a lamp when a current of 5A flows for 3 minutes. Answer: 900C

In this time 27,000 joules of electrical energy is converted into heat and light. How many joules of energy are supplied by each coulomb.

2. Relevant equations

V=W/q

E=Pt

P=VI

3. The attempt at a solution

27000/900 = 30V

P=30 x 5 = 150W

E= 150 x 180 = 2700

Have I done this correctly?
