Question

1. In electrical circuits, DC stands for (a) Direct Current. (b) Dis a. 2. When a DC volt capacitor charges up to its full capacitance age source is connected across an uncharged capacitor and a resistor in series, the (a) gradually (b) immediately. hen an uncharged capacitor is connected with a DC voltage source and a resistor in series, it charges up (a) slower in the beginning. (b) faster in the beginning. 4. The time constant Tau of a capacitor corresponds to (a) the time it takes the capacitor to discharge to 37% of its maximum charge or voltage. (b) the time it takes the capacitor to charge to 63% of its maximum charge or voltage. (c) both of the other two statements given here. 5. How do you measure the charge on the capacitor? (a) Indirectly. You measure the voltage across the capacitor since charge and voltage are proportional to each other (q CV). (b) Directly.

Explanation / Answer

2. Gradually

3. Faster in the beginning

4. (B)

5. Q= CV

So just measuring the voltage we can find charge

Option (a) is correct
