Consider three capacitors with capacitances C1 = 10 µF, C2 = 20 µF, and C3 = 30 µF connected in series and connected to a voltage source of V = 100 V. Note that if your answer is not a whole number, round it off to two decimal places. a. What is the equivalent capacitance of the three capacitors, Ceq = Blank 1 μF Your answers for Q1, Q2 and Q3 should be in scientific notation. the coefficient should be rounded off to two decimal places. Your answers for V1, V2 and V3 are real numbers rounded off to two decimal places. b. Calculate the voltage across each capacitor and the charge stored on each capacitor. Q1 = Blank 2 x 10^Blank 3 C Q2: = Blank 4 x 10^Blank 5 C Q3 = Blank 6 x 10^Blank 7 C V1 = Blank 8V V2 = Blank 9V V3 = Blank 10 V

A parallel plate capacitor has a charge on one plate of q = 1.1E-06 C. Each square plate is d1 = 1.9 cm wide and the plates of the capacitor are separated by d2 = 0.65 mm. The gap is filled with air, εo = 8.85 × 10-12 C2/Nm2. What is the voltage between the plates, ΔV, in V?

Constants How much power must be produced by the "active Na pumping" system to produce this flow against a +30-mV potential difference? Assume that the axon is 80 cm long and 30 um in diameter. During an action potential, Na ions move into the cell at a rate of about 3 x 10 mol/m s. Express your answer using two significant figures. 陌 ΑΣΦ ?
