Answer keywords:maximum resistancenetwork of resistorsseries connection

Marking scheme

  1. 1.1 mark

Hint

When the resistors are connected in series, the maximum resistance is obtained.

Quick oral answer

The maximum resistance of a network of five identical resistors of 15Ω\frac{1}{5} \Omega each can be 1Ω1 \Omega. This is because when the resistors are connected in series, the maximum resistance is obtained.

Common mistakes

  1. 1.thinking that the maximum resistance is obtained when the resistors are connected in parallel

Analysis and explanation

The maximum resistance of a network of five identical resistors of 15Ω\frac{1}{5} \Omega each can be 1Ω1 \Omega. This is because when the resistors are connected in series, the maximum resistance is obtained.

Interesting facts

The resistance of a network of resistors can be calculated using the formula for series and parallel connections.
