HW34#1 – Two batteries and internal resistance are connected in parallel across a resistance R

歡迎來到Yogi老師解題給你看,今天我要講解的是AP Physics C E&M 的問題

In the figure below, two batteries of emf ℰ = 18.0 V and internal resistance r = 0.340 Ω are connected in parallel across a resistance R.

(a)For what value of R is the dissipation rate in the resistor a maximum?

(b)(b) What is that maximum?
