1. A 100 watt lightbulb consumes how many joules of energy in 1 second?

Sagot :

Explanation:

Power of the lamp, (P) = 100 W

(a) Time, (t) = 1 s

Now, we can calculate the electrical energy consumed as:

Energy consumed = Power × Time

So,

Energy consumed = 100 × 1 J = 100 J = 100 J

So, the energy consumed is 100 J.

(b) Time (t) = 60 s

Now, we can calculate the electrical energy consumed as,

Energy consumed = Power × Time

So,

Energy consumed = 100 × 60 J = 6000 J

So, the energy consumed is 6000 J.
Answer :

Explanation:
E =(p)t
E =(100w)1s
E =100J
