Sample questions

  1. An ohmic resistor of 27 Ω has potential difference 20 V. Find current. This is a paper calculation, not a construction instruction. Round to 3 decimal places if needed. Answer in A.
  2. A constant current of 2.4 A flows for 84 s. Find transferred charge. Round to 3 decimal places if needed. Answer in C.
  3. A constant current of 1.1 A flows for 129 s. Find transferred charge. Round to 3 decimal places if needed. Answer in C.

Core

Sample questions

  1. In a theoretical circuit, 26 Ω and 11 Ω are in series across an ideal 36 V source. Find their total electrical power. Round to 3 decimal places if needed. Answer in W.
  2. In a theoretical circuit, 9 Ω and 22 Ω are in series across an ideal 16 V source. Find their total electrical power. Round to 3 decimal places if needed. Answer in W.
  3. Two branches are connected in parallel to a battery. The branch currents are 1.4 A and 1 A. What current flows through the battery? (Assume ideal wires and an ideal battery.)

Using the three versions

  • Start everyone with the same short explanation, then hand out Support, Core or Challenge.
  • Question numbers line up across the versions, so you can go through the answers with the whole class.
  • The PDF has a cover page and each version on its own pages; the answer keys PDF has all three keys.
