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
In transcranial magnetic stimulation (TMS) an abrupt decrease in the electric current in a small coil placed on the scalp produces an abrupt decrease in the magnetic field inside the brain. Suppose the magnitude of the B⃗ B→ field changes from 0.60 TT to 0 TT in 0.070 ss. Determine the induced emf around a small circle of brain tissue of radius 1.2×10−3m1.2×10−3m. The B⃗ B→ field is perpendicular to the surface area of the circle of brain tissue. Express...
Show you work. All answers should be given with two decimal places. 1. A current of 3.33 mA (IMA -0.001A) passes through a resistor which is at a temperature 22.3 °C. As a result, a voltage of 3.00 Volts is generated across the resistor. Calculate the resistance of the resistor in k 2. Rrom 2. Now the same resistor as in question 1 is immersed in liquid nitrogen (T--195.8 °C). The voltage across the resistor is still 3.00V but the...
