1. a) iii) Name an application of a combination of a p-type and n-type semiconductor. A common application is a diode. 1. b) Calculate the number of electrons that flow through a conductor if a current of 2 A flows for 4 s (charge on an electron = 1.6 × 10^-19 C). Step 1: Calculate the total charge Q that flows. The relationship between current (I), charge (Q), and time (t) is given by Q = I × t. Q = 2\, A × 4\, s Q = 8\, C Step 2: Calculate the number of electrons (n). The total charge Q is also equal to the number of electrons (n) multiplied by the charge of a single electron (e). Q = n × e n = (Q)/(e) n = 8\, C1.6 × 10^-19\, C n = 5 × 10^19 The number of electrons that flow through the conductor is 5 × 10^19.
