What happens when the separation distance between capacitor plates decreases?
The capacitance increases, and the energy stored in the capacitor increases if the voltage is kept constant.
What happens when a dielectric material is inserted between the plates of a capacitor?
The capacitance increases.
What happens when the resistance in a circuit increases, assuming voltage remains constant?
The current decreases, according to Ohm's Law (V = IR).
What is the effect of increasing resistance in a circuit with constant voltage?
The current decreases (Ohm's Law).
What happens when a dielectric material is inserted into a capacitor?
The capacitance increases, allowing it to store more energy.
What are the steps to analyze a DC circuit?
- Draw the circuit diagram. 2. Label the currents. 3. Apply KCL. 4. Apply KVL. 5. Use Ohm's Law. 6. Solve the equations.
How do you use Gauss's Law to find the electric field?
- Choose a Gaussian surface. 2. Calculate the electric flux. 3. Calculate the enclosed charge. 4. Solve for the electric field.
