A 5mA A Vs RI R2 A

In the circuit indicated in the figure, the battery has an internal resistance of 0.04 Ω. If an ammeter with a resistance of 0.04 Ω is inserted into node “a”, what is the reading of said ammeter? a) 10 Ab) 0.1 Ac) 190.1 Ad) 10.27 A

In the circuit below, if resistor R1=25.42Ω, and resistor R2=60.37Ω, what is the equivalent resistance of this circuit in units of Ohms (Ω)?

When switch S in the figure is open, the voltmeter V of the battery reads 3.10 V. When the switch is closed, the voltmeter reading drops to 2.97 V , and the ammeter A reads 1.69 A . Assume that the two Part A meters are ideal, so they do not affect the circuit. (Figure 1) Find the emf E. Express your answer in volts to three significant digits. ?
