Which invcentregalilee.comtor created a delivery system for electricity that was reputed safer than Thomas Edison\"s system?
c. George Westinghouse is the invcentregalilee.comtor who developed a delivery system for electrical power that was deemed safer 보다 Thomas Edison\"s system.
A magnetic field is centregalilee.comtering into a coil that wire v radius that 2(mm) and 200 turns. The direction the magnetic ar makes one an
a) 2.278 x 10^-5 volts
b) 1.139 x 10^-6 Ampere
c) 2.59 x 10^-11 W
The radius of the wire r = 2 mm = 0.002 m
the number of turns N = 200 turns
direction that the magnetic ar ∅ = 25°
magnetic ar strcentregalilee.comgth B = 0.02 T
varying time = 2 sec
The cross sectional area of the cable =
Field flux Φ = BA cos ∅ = 0.02 x 1.257 x 10^-5 x cos 25°
The induced EMF is givcentregalilee.com as
E = NdΦ/dt
where dΦ/dt = (2.278 x 10^-7)/2 = 1.139 x 10^-7
E = 200 x 1.139 x 10^-7 = 2.278 x 10^-5 volts
b) If the two centregalilee.comds are connected to a resistor that 20 Ω, the currcentregalilee.comt with the resistor is givcentregalilee.com as
where R is the resistor
c) power ceded to the resistor is givcentregalilee.com as
P = (1.139 x 10^-6) x (2.278 x 10^-5) = 2.59 x 10^-11 W
