A low voltage supply from which one needs high currents must have very low internal resistance. Why?

Answer the following questions: A high tension (HT) supply of, say, 6 kV must have a very large internal resistance. Why?

An energy soruce will supply a constant current into the laod, if its internal resistance is

Why should an ammeter have a low resistance?

Does current prefers to move in a high or low resistence path?

Name any one substance which has very low ignition temperature.

A current of 2A flows through a 2 ohm resistor when connected across a battery , the same battery supplies a current of 0.5A when connected across a 9 ohm resistor . the internal resistance of the battery is

If a battery of e.m.f 6.6 V can supply a current of 3A through a resistance of 1.8Omega , what curent does it supply through another resistance of 2.9Omega . Also calculate internal resistance of the battery.

Why antiseptics have low surface tension?

A cell supplies a current of 0.3 A through a resistance of 7 ohm and a current of 0.9 A through a resistance of 2 ohm. The internal resistance of the cell is
