1) A student sets up a circuit with a battery, bulb, switch, and connecting wires. The bulb glows very dimly even when the switch is fully closed. Which of the following is the most likely cause, and how should it be corrected? a) The bulb is too powerful; replace it with a lower-wattage bulb. b) The wires have loose connections or are partially stripped; ensure proper insulation removal and firm connections. c) The battery is too new; use an older battery. d) The switch is closed; open it to increase current. 2) . A circuit contains a battery, two bulbs, a switch, and an ammeter. When the switch is closed, the ammeter reads zero, and neither bulb glows. The student checks and finds the battery is charged and bulbs are functional. What is the most likely procedural error? a) Both bulbs are connected in series instead of parallel. b) The ammeter is connected in parallel with the bulbs instead of in series c) The switch is faulty and needs replacement. d) The wires are too short to complete the circuit. 3) A student is designing a circuit to test current flow using a battery, bulb, switch, and ammeter. To ensure accurate readings and safe operation, which setup is most appropriate? a) Connect the ammeter in series with the bulb and battery, and ensure all wire ends are stripped properly. b) Connect the ammeter in parallel with the bulb to prevent it from burning out. c) Use uninsulated wires to increase current for clearer readings. d) Place the switch across the ammeter to control current flow directly through it.
