Physics Questions and Answers


The following are answers to the provided questions related to electrical principles and devices:



  1. Ohm's law states that Voltage is equal to Current times Resistance. Therefore, the correct answer is: (A) Voltage = Current x Resistance.

  2. A resistor's color bands can be decoded using the color code system. The first three bands, brown (1), black (0), and red (2), indicate the value: 10 (from brown and black) followed by two zeros (from red), giving a total of 1,000 ohms. Therefore, the answer is: (A) 1,000 ohms.

  3. In the U.S., all metal equipment connected to a swimming pool must be (B) bonded together to prevent electrical hazards.

  4. Voltage can also be expressed as (D) electrical potential difference, as it represents the difference in electric potential energy between two points in a circuit.

  5. A removable memory card found in newer cellphones is often referred to as a (A) SIM card, which is used for storing mobile user information.

  6. Materials like carbon act as a (A) resistor, inhibiting the flow of current in an electric circuit.

  7. A component known as a (C) diode is a type of semiconductor that allows current to flow in one direction, commonly used for rectifying AC signals into DC.

  8. Radar can operate at frequencies as high as (C) 100,000 MHz, which is equivalent to 100 GHz, a common frequency in modern radar systems.

  9. In the electrical field, AC stands for (B) alternating current, and DC stands for direct current, describing the nature of the electrical flow.

  10. Changing AC to DC involves a process called (C) rectification, which is critical for powering DC devices from AC sources.
