1. According to Ohm's Law, if you have a simple circuit (Figure 2), what happens to the voltage and current of the resistor as the resistance increases? R Figure 2: A simple circuit. 2. If a 100 Q resistor is attached to a 5 V battery, how much current flows through the resistor? 3. If a wire's length is cut in half, what happens to the wire's resistance? 4. If a wire's area is reduced by half, what happens to the wire's resistance? 5. If the diameter and length of a wire are split in half, what happens to the resistivity, p
