About electrical circuits, batteries, Ohm\'s Law, etc Select the always true statements from the following list Ohms Law is V =I/R Resistivity is a temperature dependent material property. Ampere is the unit of current = volts/ohm A battery produces electricity by transforming chemical energy into electrical energy. In series configuration of two different value resistors the currents through each resistor will be different. Electric current in an electrical circuit is the direction that free electrons move in a conductor.

Solution

1) Not true

Ohms law V = IR

2) True

Resistivity is a temperature dependent property.

3) True

ampere is the unit of current = V/Ohm

4) True

A battery produces electricity by transforming chemical energy into electrical energy.

5) Not true

In series combinations both the currents are same.

6) Not true

Current is opposite to the direction of flow of electrons.
