Electricity Exercises

Work each problem on paper or Microsoft Word, along with a brief description of how you solved the problem.

Your work should include a step-by-step solution to the problem.

Question 1 Aluminum has a resistivity of 2.7*10-8 Ωm.  What would be the resistance of 100 m of aluminum wire with a cross-sectional area of 2*10-4 m2?

Question 2A 10 ohm resistor and a 20 ohm resistor are connected in parallel.  What is the equivalent resistance of this setup?

Question 3A 4 ohm resistor and 10 ohm resistor are connected in series.  If this circuit is connected to a 12 V battery, how much current will flow through the circuit?

Question 4A 30 ohm resistor is connected to a 1.5 V battery.  How much power is dissipated by the resistor?

Question 5Two point charges, each 6*10-5 C, are separated by 30 cm.  What is the electrostatic force produced by this arrangement?
