Can you get -5Volts as output when polarity is reversed?
yes.you can get 5v output even when the polarity is reversed. In a 5v battery, if u reverse the polarity, then u'll get the same 5v as output , but in the opposite direction.(i.e.,)-5v(negative 5 volt
How do I reduce 2000 mA or 2 Amps with 5V down to 20 mA with 5V?
assuming 5v steady the 2 amps can be virtual zero by reducing the load present
How does an IC 7805 works?
in the IC-7805 i need a meaning for the number 7,8,0,5 seperately
What is nominal zener voltage?
A zener diode has a voltage when it reachesbreak over it may be 5v 12vor other voltage as manufactured. The manufacture will produce a 5v zener or is it? This voltage can change from device to device but the mean or nominal voltage will be as close as 5v as possible. So when buying a 5v zener do not expect 5v absolute but a nominal 5 v ZENERS are designed for a specific voltage [ THEREFORE NOMINAL] as mentioned above . depends on the voltage required it can be bought within a specific voltage -/+ a % of the breakdown
Difference between inverter and pwm control?
One invert the function or a signal. the other is a pulse width modulator controller which are usually used to convert one source of power to another. As in 12v dc in 5v dc out or vice versa
