Homework Statement
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.
Homework Equations
V=W/q
E=Pt
P=VI
The Attempt at a Solution
27000/900 = 30V
P=30 x 5 = 150W
E= 150 x 180 = 2700
Have I done this correctly?
