Question 92
Many homes and schools are connected to electricity supplies.
People who use the electricity pay for how much they use.
Task 1
Work individually for this task.
Find out how much current some electrical items use. Do not include items that work only on batteries.
For example, most phone chargers use about 1.5 A.
When searching for this information, you may find a number with the unit W. This is not the current. You can find the current by dividing this number by the voltage. In most countries, the voltage is about 230 V. In some countries, the voltage is 110 V or 120 V. For example, if you find something with 500 W, and your voltage is 230 V, the current used is 500/230 = 2.2 A.
