Question

Explain internal resistance.​

Answer 1

$\huge{\underline{\underline{\mathfrak{Answer}}}}$

➡️ Internal resistance usually means the electrical resistance inside batteries and power supplies that can limit the potential difference that can be supplied to an external load. With an external resistance of 0.001 Ohms, you have basically a short circuit.

Answer 2

Answer:

▶Here's your answer

⏩Internal resistance usually means the electrical resistance inside batteries and power supplies that can limit the potential difference that can be supplied to an external load....

⏩Batteries and cells have an internal resistance (r) which is measures in ohm's (W).

⏩When electricity flows round a circuit the internal resistance of the cell itself resists the flow of current and so thermal (heat) energy is wasted in the cell itself.....
