Worked Solution & Example Answer:A student sets up a circuit using a diode, a lamp and a variable resistor, as shown in Fig - OCR Gateway - GCSE Physics - Question 17 - 2021 - Paper 1
Step 1
Draw a cell in the circuit
Answer
To illustrate the correct way to draw a cell that would power the lamp, position the cell symbol in the circuit between the diode and the variable resistor. Ensure that the positive terminal of the cell connects to the diode while the negative terminal leads to the variable resistor. This arrangement allows the current to flow through the circuit efficiently, enabling the lamp to light up.
