... • It's the energy in the circuit which flows fast, not the electrons. • Metals are always full of movable electrons. In a simple circuit, all of the wires are totally packed full of electrons all the time. And when a battery or generator pumps the electrons at one point in the circuit, electrons in ...

... There are usually two divisions for current measurements: one for small currents and one for large currents. You should work with the big scale if the current you are trying to measure can be bigger than the value of the small scale. DC/AC selection should be performed. We will be working with DC si ...
