3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What is q1?
Show answer
Write the potential-divider equation for the output taken across the lower resistor R2R_2. [1 mark]
What is q2?
Show answer
A divider has R1=R2=1.0 kΩR_1 = R_2 = 1.0\ \text{k}\Omega across 6.0 V6.0\ \text{V}. Find the output across R2R_2. [2 marks]
What is q3?
Show answer
State what happens to a divider's output when a low-resistance load is connected across it, and why. [2 marks]
