← Silicon is doped with donors, 4.0 × 10²⁰ in each cubic metre. At room temperature ni = 1.0 × 10¹⁶ m⁻³. Assume that every donor gives one electron. How many holes are there in each cubic metre?A small lamp of fixed resistance 260 Ω is in a loop with a cell of 6.4 V and a germanium diode. The diode is connected so that it conducts, and it drops 0.3 V. How much current does the lamp carry? →
