Hello:
I am working on a school project that needs me to make a transistor circuit.
im using a tip102 npn transistor, here is a link for the spec sheet:
http://www.datasheetcatalog.com/datasheets_pdf/T/I/P/1/TIP102.shtml
when the base receives a 5V signal, the collector is hooked up to the positive end of a 12V car battery. this is connected to a solenoid that is then grounded.
when i hook everything up there is no clicking from the solenoid (it isnt turning on obviously). what could this be? i looked at the datasheet of a tip102 and it seems fine.
thanks
edit: the solenoid is 12V, 540mA, 6.5W
