1. Construct a closed circuit with a battery, resistor and an ammeter. Connect voltmeter across the resistor.
2. Change the voltage of the battery and record current and potential difference.
Voltage V Current I
5
10
15
20
25
30

3. Plot a graph of V Vs I. Find the slope. The slope gives you experimental value of resistance. Compare you experimental value of resistance to known (standard) value. Find percent difference of two values.
4. Repeat procedure 1-3 for two resistors connected in series. Slope gives you equivalent resistance of two resistors in series. This is your experimental value of resistance. Compare this experimental resistance to known resistance( equivalent resistance of two resistors) and fine percent difference.
5. Repeat procedure 1-3 for two resistors connected in parallel. Slope gives you equivalent resistance of two resistors in parallel. This is your experimental value of resistance. Compare this experimental resistance to known resistance( equivalent resistance of two resistors) and find percent difference.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
