Worked Solution & Example Answer:Consider the circuit containing an LED drawn on the right - Junior Cycle Science - Question d - 2016

Step 1

What is observed when the switch is closed?

96%

114 rated

Answer

When the switch is closed, the LED in the circuit lights up. This is because closing the switch completes the circuit, allowing current to flow through the LED, which causes it to emit light.

Step 2

What, if any, is the effect of reversing the terminals of the battery?

99%

104 rated

Answer

If the terminals of the battery are reversed, the LED would not light. This is due to the fact that LEDs are polarized components, meaning they only allow current to flow in one direction. Reversing the battery terminals reverses the current flow, preventing the LED from functioning.
