Homework Help: Maths

Posted by David on Saturday, November 17, 2012 at 3:05am.

3. Ohm’s law states that the current flowing in a circuit varies directly as the applied voltage and inversely as the resistance. In an experiment, the resistance was increased by triple the percentage by which the voltage was increased. A student calculated the percent change in current to be 15%. Is the student correct?
• If yes, determine the percent change in voltage and resistance to three significant digits.
• If no, explain why and give an example of non-zero percent changes in V and R that would result in a 15% increase in I.
