Transcript
hello everyone good afternoon so welcome to board brahmasra and today we are going to start with the electricity chapter I know a lot of you are very curious and waiting for this chapter this is bit difficult because it is not very intuitive why current will flow in such a particular direction why there is a voltage why there is potential differenc...

Questions & Answers
Q: What is the difference between conductors and insulators?
Conductors allow the flow of electric current, while insulators resist the flow of current. Conductors typically include metals such as copper and silver, while insulators include materials like rubber and glass.
Q: What is Ohm's Law and how is it applied?
Ohm's Law states that the potential difference (voltage) across a conductor is directly proportional to the current and inversely proportional to the resistance. It is applied to calculate unknown values of voltage, current, and resistance in a circuit.
Q: What is resistivity and how does it affect resistance?
Resistivity is the property of a material that determines its resistance per unit length and per unit crosssectional area. Higher resistivity values result in higher resistance, while lower resistivity values result in lower resistance.
Q: How does the potential difference across a circuit affect the flow of current?
The potential difference, or voltage, across a circuit determines the rate at which electric charges flow. Higher voltage results in higher current, while lower voltage results in lower current, assuming the resistance remains constant.
