A metallic resistor is connected across a battery. If the number of collisions of the free electrons with the lattice is some how decreased in the resistor (for example, by cooling it), the current will

When a 4Omega resistor is connected across the terminals of a 12V battery, the number of coulombs passing through the resistor per second is:

A resistor is connected across a battery and current flows through it. Compare the potential energy of an electron before entering the resistor be that after leaving the resistor.

Six 18.0Omega resistors are connected in parallel across a 12.0V ideal battery. What is the current through the battery?

Three resistors are connected to a 6 V battery as shown in the figure given below : Calculate : potential difference across the 7.2Omega resistor.
