## Frequently asked Questions on CBSE Class 12 Science: Current Electricity

Q1

### What is ‘Electrical resistance’?

Resistance to electricity also known as electrical resistance, is a force that counteracts the flow of current.

Q2

### What is a ‘Series connection’?

The definition of series connection in the dictionary is a circuit in which positive and negative cells are connected, thus increasing voltage.

Q3

### What does the ‘Ohm’s law’ state?

Ohm’s law, description of the relationship between current, voltage, and resistance. The amount of steady current through a large number of materials is directly proportional to the potential difference, or voltage, across the materials.
