Will putting two batteries in parallel make the power supply last longer by doubling mA-hr capacity, or will it force twice the current through a current sensitive circuit?
If the circuit has a known power demand with 5V input and draws a precise amount of current, but the circuit is powered by a 9V but doesnt...
You have not researched the subject sufficiently. Your social circle does not include those females who are interested in an Engineering Career.
Electric powered aircraft seem like a pipe dream. Airlines make money by keeping their planes full and in the air. Charging or swapping batteries would be much less efficient than filling a tank with Jet A. The power required to get a 747 off the ground is around 90 mega watts. That is one serious battery.
From the data sheet:
Wide Power Supply Range:
– Single Supply: 3V to 32V
– Or Dual Supplies: ±1.5V to ±16V
Your math is correct but you are ignoring the resistance of the human body. A voltage difference of 0.0000000001 volts wouldn't introduce anything like the current you calculated. That's why a 9V battery doesn't immediately kill you if you touch the positive and negative...
God will tell you.
I have power strip with 4 plug points. There is only one switch to turn them one. If i am using only one plug point then do the rest consume electricity?
I’ve done a lot of research online about making an hho generator and torch and have put one together. Starting small, I used a glass jar with 4 steel plates 1”x3”, insulated between and alternating positive and negative to connect to a car battery, putting salt water in the jar, a 1/4 hose coming out going to a...
