Wire 1 / Draad 1 Wire 2 / Draad 2 Consider the figure above. It shows a conductor (wire 1) with length L and resistivity p, which is welded to another conductor (wire 2) with length L and resistivity P2. The temperature coefficients of resistivity of wire 1 and wire 2 are a, and a2. respectively. Determine an expression for the temperature coefficient of resistivity for the combined wire. Choose the answer from the list below. Beskou die figur hierbo. Dit toon'n geleier (draad 1) met lengte Len resistiwiteit p, wat vasgemaak is aan 'n tweede geleier (draad 2) met lengte & en resistiwiteit p2: Die temperatur koeffisiente van resistiwiteit van geleier 1 en geleier 2 is a, en a2, respektiewelik. Verkry 'n uitdrukking vir die temperatur koeffisient van resistiwiteit van die saamgestelde geleier. Kies die antwoord vanuit die lys hieronder. :a.
