Question

Two circuits made up of identical ideal emf devices (E- 1.64 V) and resistors (R-39.00) are shown in the figure below. What is the potential difference V - V, for the following circuits? Circuit Circult 2 (a) for circuit 1 V (b) for circuit 2 V What is the current in the resistor for the following circuits? (c) in circuit 1 (d) in circuit 2 A

Answer 1

(1) the potential difference

(a) for circuit 1

$V_{1ab}=\epsilon$

$V_{1ab}=1.64V$

(b) for circuit 2

$V_{2ab}=2\epsilon$

$V_{2ab}=3.28V$

(2)

(a) the current for circuit 1

$I_{1ab}=V_{1ab}/R$

$I_{1ab}=1.64/39.0$

$I_{1ab}=0.04A$

(b) for circuit 2

$I_{2ab}=V_{2ab}/R$

$I_{2ab}=3.28/39.0$

$I_{2ab}=0.08A$
