Exercise 2: Resistance and power.

A 4,5V battery is connected to a 200Ω resistor. Calculate the value of the crossing current (I) and the power dissipation (P).

Write the answers in a google drive spreadsheet; then make an entry in your blog with a link to the document.

 Due date: Sunday, October 7th, 2012.

Resistance and power


Resistors are designed to provide a constant and known resistance to the flow of the current. They are used to obtain a lower voltage than that provided by the power source.
