Question

1.

A) A 13-Ω coffee maker and a 16-Ω frying pan are connected in series across a 120-V source of voltage. A 25 Ω bread maker is also connected across the 120-V source and is in parallel with the series combination. Find the total current supplied by the source of voltage.

B) A new "D" battery has an emf of 1.5 V. When a wire of negligible resistance is connected between the terminals of the battery, a current of 25 A is produced. Find the internal resistance of the battery. Ω

C)A galvanometer has a full-scale current of 0.200 mA and a coil resistance of 50.0 Ω. This instrument is used with a shunt resistor to form an ammeter that will register full scale for a current of 60.0 mA. Determine the resistance of the shunt resistor.
