Why does connecting a battery''s positive terminal to the negative ...
The positive of battery 2 is now at 18V relative to ground because it is always 9V above its own negative terminal at equilibrium. As for a short circuit, in order to get a short circuit, I have to provide a complete circular path for current to flow through. I can do this by adding another wire between any two terminals.
Understanding Short Circuits: Causes, Prevention, and Solutions
A ground fault short circuit occurs when a charged wire unintentionally touches a grounded section of any equipment. Common contact points for live cables include appliances, circuit boxes, and outlets. Causes of Short Circuits. Several electrical issues can cause wiring to short circuit. It''s important to be aware of these causes: 1.

RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from …
Why is a capacitor considered a short circuit at start up?
If we use a capacitor that has a decoupling capacitor, so shunted to ground, then why for a DC source do we say the capacitor acts like a short at startup (t=0) thus having a high inrush but according to the top paragraph a DC source has a 0 Hz frequency so it has a very high impedance. This clearly is a contradiction.
Capacitor Failures
Capacitors, like batteries, have internal resistance, so their output voltage is not an emf unless current is zero. This is difficult to measure in practice so we refer to a capacitor''s …
