In the circuit, R = 21 kΩ and C = 0.56 μF. The capacitor is allowed to charge fully and then the switch is changed from position a to position b. What will the voltage across the resistor be 1.7 ms later?

78 V

Explanation:

The figure of the circuit is missing: find it in attachment.

At the beginning, the switch is in the position "a", so the current flows from the battery through the resistor and the capacitor. So, the capacitor charges.

The final charge on the capacitor is given by:

where

is the capacitance

is the final potential difference across the the capacitor (equal to that of the battery)

So,

Later, the switch is moved to position b, so now the capacitor will discharge through the resistor. As a result, the current in the circuit follows the law

where

is the resistance

And according to Ohm's law, the voltage across the resistor is given by

Therefore,

However, (potential difference across the battery), so

Therefore, substituting

t = 1.7 ms = 0.0017 s

We find:

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
