Current produced by thermocouples. My understanding is that the thermocouple voltage is strictly a function of the temperature. Apparently this is called the Seebeck Voltage. Like any voltage source there is an internal resistance associated with it due to real world effects.
HIV/AIDS. Condoms for HIV prevention. Condoms, when used correctly and consistently, are highly effective in preventing HIV and other sexually transmitted infections (STIs). A large body of scientific evidence shows that male latex condoms have an 80% or greater protective effect against the sexual transmission of HIV and other STIs.
If used correctly condoms are 98% effective. Withdrawal is up to 96% effective when done correctly (always practiced). By using both methods every time you have s â¦ ex the chance of pregnancy would be about 1 in 100 or the same as Birth Control Pills.
