Question

1. a resistor is any object that uses ________ to do work.
2. in a series circuit, charges have only ________ path to move.
3. if one item breaks in a series circuit, ________ will move through the circuit.
4. the sum of potential drops in a series circuit equals the potential ________ across the battery.
5. in series circuits, charges lose ________ energy as they pass through resistors.
6. in parallel circuits, charges can move through several ________.
7. more current flows through the branch with ________ resistance.
8. both series and parallel circuits shown are examples of ________ current (dc).

Explanation:

1. Resistors use electrical energy to perform work.
2. In a series circuit, there is a single - path for charges to move.
3. If one item breaks in a series circuit, no charges will move as the circuit is broken.
4. The sum of potential drops in a series circuit equals the potential difference across the battery.
5. Charges lose electrical potential energy as they pass through resistors in series circuits.
6. In parallel circuits, charges can move through multiple paths.
7. More current flows through the branch with lower resistance according to Ohm's law.
8. Both series and parallel circuits shown are examples of direct current (DC) circuits.

Answer:

1. electrical energy
2. one
3. no charges
4. difference
5. electrical potential
6. paths
7. lower
8. direct
