Question: 1. Using the formulas for series and parallel circuits, fill in the blanks in the table below for the circuit of Fig. 2. A cell

1. Using the formulas for series and parallel circuits, fill in the blanks in the table below for the circuit of Fig.

Ri Battery 35.0 v K5.00 v 5.00 V V 2.75 A 1.95

2. A cell has an emf of 1.44 V and an internal resistance of 0.0550Ω. If there is 0.135 A in the cell, what voltage is applied to the external circuit?

3. The voltage applied to a circuit is 12.0 V when the current through the battery is 0.858 A. If the internal resistance of the battery is 0.245Ω, what is the emf?

Ri Battery 35.0 v K5.00 v 5.00 V V 2.75 A 1.95 A 2.80 0.97 A 7.50 V
