**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} m^{2}?

**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**
