CSEC Physics · January 2016 · Paper 2 · Question 6(b)(i)

A Physics class was given a circuit diagram as shown in Figure 8. Use Figure 8 to answer the three questions posed to the class. Given that the formula for the equivalent resistance of two resistors R₁ and R₂ in parallel is R = R₁R₂ / (R₁ + R₂),

calculate the equivalent resistance across BC.

This question uses a figure or table from the paper — you'll see it when you practise.
