# Electrical and Electronic Engineering watch

1. Hi, im stuck on a question which we had in a mock exam and can't seem to find any solutions online. The question is; Four cells are arranged in series in a battery pack. Each cell creates an e.m.f of 1.5v and has an internal resistance of 1ohm. Given that the battery pack is connected to an external load of variable resistance, calculate the maximum power that the pack can supply to the load? You are also given the resistance is 120ohms and is operated at 240V supply, power consumed whilst operating is 2kW. Can anyone help me out? Thanks

Have you any notes on the maximum power transfer theorem?

is this a different question ??
