For the circuit shown, the value of current at time $t = 3.2$ s will be ______ A.
[Voltage distribution $V(t)$ is shown by Fig. (1) and the circuit is shown in Fig. (2)]
Numerical value type. Enter your answer.
Answer: 1
Between $t = 3$ s and $4$ s, $V$ rises from $5$ V to $10$ V, i.e. $5$ V/s. At $t = 3.2$ s: $V = 5 + 5(0.2) = 6$ V.
The $5$ V battery opposes the source:
$$I = \frac{6 - 5}{1} = 1\ \text{A}$$
