When the switch is closed, the voltmeter reading drops to 2.93 V, and the ammeter A reads 1.67 A. Assume that the two meters are ideal, so they don't affect the circuit. Find the emf Submit My Answers Give Up Figure 1 of 1 Part B Find the internal resistance of the battery Submit My Answers Give Up Part C Find the circuit resistance R. 4101

Explanation / Answer

A) emf = 3.09 V

B) r = 0.16 / 1.67 = 0.095

C) R = 2.93 / 1.67 = 1.75
