CAPE Physics Unit 2 · 2008 (T&T) · Paper 1 · Question Q15
Item 15 refers to the following diagram. The device above represents a potential divider. The expression used to determine the output voltage is
- (A)
V_o = I (R_1 + R_2) - (B)
V_o = V_{in} \left(\frac{R_1 + R_2}{R_1}\right) - (C)
V_o = V_{in} \left(\frac{R_1}{R_1 + R_2}\right) - (D)
V_o = I (R_1 + R_2)
