Question

if an incandescent light bulb used for lighting has an efficiency rating of 5 percent, then for every 1.00 joule of electrical energy consumed by the bulb, which of the following is produced?

Answer 1

0.05

Step-by-step explanation:

You should list the choices.

Efficiency = energy used / energy need * 100%

Efficiency = 5%

energy used = ?

energy needed = 1

Formula

Efficiency = energy used/energy needed * 100

100 * efficiency * energy needed = energy used.

Solution

1.00 * 5% = 1.00 * 5/100 = 1.00 * 0.05 = 0.05

Your answer should be something resembling 0.05 Joules
