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

Question 3: A 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 4: A 30 ohm resistor is connected to a 1.5 V battery. How much power is dissipated by the resistor?

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