If only 470 Ω and 220 Ω resistors happen to be available and we need a resistance of 370 Ω, determine a combination of one 470 Ω and two 220 Ω resistors that will theoretically come within 1 Ωof the desired 370 Ω. Now with ±5% tolerance of the individual resistors used, what could be the maximum and minimum effective resistance of your circuit due to resistor tolerance?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
