Answer 1

Here are the answers to your questions:

Question 1: Which analogy best describes voltage?

• Answer: pressure of water moving through a pipe

Question 2: Which analogy best describes amperage?

• Answer: diameter of a pipe through which water moves

Question 3: Which analogy best describes resistance?

• Answer: length of the pipe through which water moves

Question 4: The current in a circuit is halved. What happens to the resistance?

• Answer: The resistance is doubled. (Using Ohm's Law, if V is constant and I is halved, R must increase.)

Question 5: A flashlight has four 1.5-volt batteries. The bulb has a resistance of 2.4 ohms. What is the amperage of the circuit?

1. Calculate the total voltage from the batteries: 4 batteries × 1.5 volts = 6 volts
2. Use Ohm's Law (V = IR) to find the current:
   • I = V / R
   • I = 6 volts / 2.4 ohms = 2.5 A

• Answer: 2.5 A
