If you estimate 0 ~ 10-11, what is the area of the plates to have a 1.0 Farad capacitance?
If you estimate 0 ~ 10-11, what is the area of the plates to have a 1.0 Farad capacitance? A bank of three capacitors (C1, C2, C3) is connected as follows. C2=1 F What is the effective total capacitance of the bank? A light bulb is attached to a battery with constant voltage V. The light filament has resistance R. When the light bulb is first turned on by attaching to the battery, the filament heats up rapidly, and as it heats, its resistance R increases (due to increased scattering of electrons by thermal vibrations). As the light bulb filament heats up, the current i in the filament A) Increases B) Decreases C)Remains the same. An ideal battery produces a fixed? Two cylindrical resistors are made of the same material (same resistivity ). Resistor 2 is twice as long and has twice the diameter of resistor 1. What is the ratio R2/R1?
