3. A platinum wire of resistance 5 ohms has 4[amperes] of electric current flowing through it. (3a) How many electrons are entering (and leaving) the wire per second, and why? (3b) What is the voltage drop across this wire in Volts? (3c) What is the magnetic field magnitude at a distance of 5[mm] away from the wire
Answer 4 & 5 please! thank you! R values = Resistor value, R1 = 990 Ohms Resistor value, R2 = 2050 Ohms 4. Connect the 2nd resistor in parallel with the 1st resistor and connect that combination to the battery. Measure the following: The current passing through the R1, I1 = ___0.0058____ A The current passing through the R2, I2 = ___0.0031____ A The current supplied by the battery, I = ___0.0092____ A Calculate I1 + I2 =...
please answer all questions A proton and an electron enter a uniform magnetic field. The velocity vector of each particle is perpendicular to the magnetic field. If their circular orbits have the same radii, what is the ratio of their speeds (Velectron/ proton)? O 5.5E-4 O 0.5 O 1.0 04.0 1800 A horizontal length of current-carrying wire is suspended from two identical flexible leads that are under tension due to the weight of the wire. The wire is oriented at...
4. a) Reference: 1"e”-1.6x10-1, Coulombs of In biology, a cell membrane cause can cause separation of charge by selectively letting one type of ion through the membrane while holding out the other type. Suppose that a cell membrane allows 4 x10 pass through, each singly ionized (one extra electron each) a) How much charge passed through the membrane TO negative ions t b) If this charge passed through the membrane in 25 msec (millisconds), then what was the average curent...
