NOTE: THE AMMETER IS IN FACT LIKE A WIRE IN THE CIRCUIT – HAS NO RESISTANCE AM1 SW1 R4 SW2 BAT1 R2 9Ω R1 R3 9 V 1) What is the current through the battery when the switch SW1 is CLOSE and the switch Sw2 is OPEN? 2) In the conditions of the previous question (the switch SW1 is CLOSE and switch SW2 is OPEN), is the current through the battery equal to the reading on the amperemeter? Justify your answer. 3) What is the current through the battery when the switch SW1 is OPEN and the switch SW2 is CLOSE? 4) In the conditions of the previous question (the switch SW1 is OPEN and the switch SW2 is CLOSE), is the current through the battery equal to the reading on the amperemeter? Justify your answer.

A battery with an emf of 9 [V] is connected to a 2 [kΩ] resistor. How much energy is dissipated in the resistor in 1 hour ?

To measure currents as shown, you would replace a wire between two points with an ammeter. Specify the points between which you would place an ammeter to measure the following:                                                                  (a) the total current; (b) the current flowing through R1 ; (c) through R2 ; (d) through R3 . Note that there may be more than one answer to each part.
