Thank you very much, your help was precious.

Please help with the following exercise: Given 2 resistors in series R1=10 ohms, R2= 30 ohms, determine the current flowing through the resistors and the voltage across each resistor, if the potential difference across the wire is V=12V. This is how I solved it: The total resistance Req=...

Please help with the following exercise: How much should the electrical resistance of a light bulb be in order to consume a power of 60W if a voltage of 220V is applied? This is how I solved it: Power= Voltage^2 / Resistance 60W = 220V^2 / R R = 807 ohms Is it correct? Thank you.

Please help with the following exercise: Two conductor spheres with radius R and 2R are at a great distance one from the other. We put a charge of Q=+1.7C on the smaller sphere, and then we put them in contact with a conductor thread. Determine what charge the spheres will have at...

Hi, I need help with the following exercise: Homework Statement We have a square circuit, with 4 capacitors, 1 on each side of the square, all with the same capacitance C. Calculate the total capacitance of the system of capacitors between the two diagonally opposite corners of the square, A...

The physical terms might not be the right english ones, I am not english. I hope you will understand anyway. I need help with the 3 following exercises, if anyone could dedicate some time to them I would be really grateful. Thank you. 1) Determine the electric and potential fields in all the...

The volume of a cylinder, with adiabatic walls and closed at the ends, has been divided in two parts by an adiabatic plate (with unimportant volume), which can slide without friction inside the cylinder (it is like a movable piston). The cylinder has been filled with an ideal diatomic gas...

I tried but I cannot do it. Please help. Two rigid adiabatic containers have inside the same ideal gas, respectively N1=3mol at a temperature T1=340K and N2=2mol at a temperature T2=280K. The two containers come into contact by opening a faucet, and the gas mixes, getting to a temperature T3...
