Electronic Devices and Circuits - Engineering
Q1: The unit of thermal resistance of a semi-conductor device isA Ohms
B Ohms/°C
C °C/ohm
D °C/watt
ANS:D - °C/watt The SI units of thermal resistance are kelvins per watt or the equivalent degrees Celsius per watt (the two are the same since the intervals are equal: Δ1 K = Δ 1 °C). The thermal resistance of materials is of great interest to electronic engineers because most electrical components generate heat and need to be cooled. |
