- A capacitor is constructed out of a pair of perfectly aligned rectangular metal plates with a small air gap between them. The capacitor is connected to a 1.5 V battery. Then, without disconnecting the battery, the capacitor is dipped into a beaker of silicon oil so that the rectangular plates become half- submerged in oil. Which of the following quantities stays the same after the capacitor is partially dipped in silicon oil (select all that apply)? The amount of charge in the silicon oil The voltage across the capacitor O The electric field strength in the space between the plates of the capacitor O The total capacitanceJimmy has a battery connected across a peice of conducting wire. If Jim wants to create greater power dissipation in the wire , he should : a. Make the wire longer b. Increase the diameter of the wire cross section c. Increase the resistivity of the wires matierial d. Increase the temperature e. Decrease the battery voltageSuppose a computer manufacturer can build circuit boards according to the following process: 12 resistors + 20 insulators + 8 memory chips → 4 circuit boards. How many circuit boards could you make using 35 insulators, assuming you have enough of all the other parts? A) 20 B) 4 C) 10 D) 7
- discussion problem 4: Why does the voltage across the capacitor (and neon tube) decrease as the capacitor is discharging? math-physics problem 1: Show that the flow of charge on the capacitor is dq Vbatt – q/C %3D dt R where Vhatt is the voltage across the battery, R is the resistor, and C is the capcitence. To do this you will need to apply Kirchoff's loop law. Also, the method of the RC circuit in the book is very similar (check the book).SUBJECT: PHYSICS11-13
