Consider two different capacitors in series. What sentence(s) is/are correct?a. Charge in each capacitor will be the same b. Voltage across different capacitor will be different c. Voltage across different capacitors is the same d. Charge in each capacitor will be different

a and b are correct

Explanation:

This is because, the total voltage V across capacitors in series equals sum of voltages on each capacitor.

So, V = V₁ + V₂

Since the same current flows in each capacitor in series, the charge is the same. So Q = Q₁ = Q₂

Q/C = Q₁/C₁ + Q₂/C₂ = Q/C₁ + Q/C₂

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
