Question

An iron has a power of 1,000W. How much energy will it electrically transfer each second?

Answer 1

`\[ \text{Energy (in joules)} = \text{Power (in watts)} * \text{Time (in seconds)} \]`

`\[ \text{Energy (in joules per second)} = 1,000 \, \text{watts} * 1 \, \text{second} \]`

`\[ \text{Energy (in joules per second)} = 1,000 \, \text{joules} \]`

Therefore, the iron will electrically transfer 1,000 joules of energy each second.
