Immediately after the switch is closed, determine the value of the charge Qon the capacitor, the voltage Von the capacitor. Also, find the current ithrough the 20-Ω resistor (R3) that is in parallel with the capacitor. Make sure you clearly explain your reasoning.

See explanation.

Explanation:

Immediately after the switch is closed the capacitor, which was initially discharged, has had not enough time to collect any charge; therefore, the charge on the capacitor is zero.

Also, since there is no charge on the capacitor, there is no potential difference (voltage) across the capacitor immediately after the switch is closed.

Going around the circuit gives

where is the current through resistors , , and is the current through .

Now since there is no potential across the capacitor, the current is not divided at the junction; therefore, , which gives

which is the current through immediately after the switch is closed.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
